package/linux-tools: don't register each tools twice

Because each tool's individual .mk files is included from the top-level
Makefile and we also include them from linux-tools.mk, they get
registered twice, and thus built twice, and thus installed twice.

We did include them from linux-tools.mk to guarantee they would be
included early and each tool had a chance to register itself before we
were to construct the build and install hooks.

However, the ordering is _currently_ guaranteed, in the C locale by the
files names, which we anyway sort using make's $(sort) function, which
always sorts in the C locale.

Beware if we are to ever rename those files in the future...

fatal error: stdlib.h: No such file or directory
 #include_next <stdlib.h>
                         ^
compilation terminated.
```

The C++ library in GCC 6 now provides its own `<stdlib.h>` header that
wraps the C library header of the same name, so in `<cstdlib>` the
header include

```
#include <stdlib.h>
```

has become

```
#include_next <stdlib.h>
```

`#include_next` is sensitive to the order of directories in the
preprocessor's search path, so if that order is changed with `-isystem`
then the compiler can't find the right header:

```
[1] /usr/arm-buildroot-linux-gnueabihf/sysroot/usr/include
[2] /opt/ext-toolchain/arm-buildroot-linux-gnueabihf/include/c++/6.1.0
[..]
End of search list.
```

`<cstdlib>` is located in [2] whereas `<stdlib.h>` (C library header) is
in [1]. In this case, the `#include_next <stdlib.h>` statement in
`<cstdlib>`, located in [2], is evaluated **after** the search path [1],
so the compiler does not find the right system header.

The problem here is that the OLA build system replaces the `-I` in the CFLAGS
from libprotobuf with `-isystem` to fix some warnings treated as errors
in the libprotobuf header files.

`-isystem` should be used to suppress warnings in system headers only
and the libprotobuf header files are not system files.

The correct fix is to compile with less restrictions and remove
`-Werror` for the build. This is already done by passing
`--disable-fatal-warnings` to OLA.

Fix the reordering of the GCC search paths by removing the replacement of
`-I` with `-isystem`.

linux/tools: make it a real, separate package

The kernel source tree also contains the sources for various userland
tools, of which cpupower, perf or selftests.

Currently, we have support for building those tools as part of the
kernel build procedure. This looked the correct thing to do so far,
because, well, they *are* part of the kernel source tree and some
really have to be the same version as the kernel that will run.

However, this is causing quite a non-trivial-to-break circular
dependency in some configurations. For example, this defconfig fails to
build (similar to the one reported by Paul):

    BR2_arm=y
    BR2_cortex_a7=y
    BR2_ARM_FPU_NEON_VFPV4=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_INIT_SYSTEMD=y
    BR2_LINUX_KERNEL=y
    BR2_LINUX_KERNEL_CUSTOM_GIT=y
    BR2_LINUX_KERNEL_CUSTOM_REPO_URL="https://github.com/raspberrypi/linux.git"
    BR2_LINUX_KERNEL_CUSTOM_REPO_VERSION="26f3b72a9c049be10e6af196252283e1f6ab9d1f"
    BR2_LINUX_KERNEL_DEFCONFIG="bcm2709"
    BR2_PACKAGE_LINUX_TOOLS_CPUPOWER=y
    BR2_PACKAGE_CRYPTODEV=y
    BR2_PACKAGE_OPENSSL=y
    BR2_PACKAGE_LIBCURL=y

This causes a circular dependency, as explained by Thomas:

 - When libcurl is enabled, systemd depends on it

 - When OpenSSL is enabled, obviously, will use it for SSL support

 - When cryptodev-linux is enabled, OpenSSL will depend on it to use
   crypto accelerators supported in the kernel via cryptodev-linux.

 - cryptodev-linux being a kernel module, it depends on linux

 - linux by itself (the kernel) does not depend on pciutils, but the
   linux tool "cpupower" (managed in linux-tool-cpupower) depends on
   pciutils

 - pciutils depends on udev when available

 - udev is provided by systemd.

And indeed, during the build, we can see that make warns (it's only
reported as a *warning*, not as an actual error):

    [...]
    make[1]: Circular /home/ymorin/dev/buildroot/O/build/openssl-1.0.2h/.stamp_configured
    <- cryptodev-linux dependency dropped.
    >>> openssl 1.0.2h Downloading
    [...]

So the build fails later on, when openssl is actually built:

    eng_cryptodev.c:57:31: fatal error: crypto/cryptodev.h: No such file or directory
    compilation terminated.
    <builtin>: recipe for target 'eng_cryptodev.o' failed

Furthermore, graph-depends also detects the circular dependency, but
treats it as a hard-error:

    Recursion detected for  : cryptodev-linux
    which is a dependency of: openssl
    which is a dependency of: libcurl
    which is a dependency of: systemd
    which is a dependency of: udev
    which is a dependency of: pciutils
    which is a dependency of: linux
    which is a dependency of: cryptodev-linux
    Makefile:738: recipe for target 'graph-depends' failed

Of course, there is no way to break the loop without losing
functionality in either one of the involved packages *and* keep
our infrastructure and packages as-is.

The only solution is to break the loop at the linux-tools level, by
moving them away into their own package, so that the linux package will
no longer have the opportunity to depend on another package via a
dependency of one the tools.

All three linux tools are thus moved away to their own package.

The package infrastructure only knows of three types of packages: those
in package/ , in boot/ , in toolchain/ and the one in linux/ . So we
create that new linux-tools package in package/ so that we don't have to
fiddle with yet another special case in the infra. Still, we want its
configure options to appear in the kernel's sub-menu.

So, we make it a prompt-less package, with only the tools visible as
options of that package, but without the usual dependency on their
master symbol; they only depend on the Linux kernel.

Furthermore, because the kernel is such a huge pile of code, we would
not be very happy to extract it a second time just for the sake of a few
tools. We can't extract only the tools/ sub-directory from the kernel
source either, because some tools have hard-coded path to includes from
the kernel (arch and stuff).

Instead, we just use the linux source tree as our own build tree, and
ensure the linux tree is extracted and patched before linux-tools is
configured and built.

support/scripts/get-developers: add new script

This script, and its companion library, is more-or-less Buildroot's
equivalent to the kernel get_maintainer.pl script: it allows to get the
list of developers to whom a set of patches should be sent to.

To do so, it first relies on a text file, named DEVELOPERS, at the root
of the Buildroot source tree (added in a followup commit) to list the
developers and the files they are interested in. The DEVELOPERS file's
format is simple:

N:     Firstname Lastname <email>
F:     path/to/file
F:     path/to/another/file

This allows to associate developers with the files they are looking
after, be they related to a package, a defconfig, a filesystem image, a
package infrastructure, the documentation, or anything else.

When a directory is given, the tool assumes that the developer handles
all files and subdirectories in this directory. For example
"package/qt5/" can be used for the developers looking after all the Qt5
packages.

Conventional shell patterns can be used, so "package/python-*" can be
used for the developers who want to look after all packages matching
"python-*".

A few files are recognized specially:

 - .mk files are parsed, and if they contain $(eval
   $(<something>-package)), the developer is assumed to be looking after
   the corresponding package. This way, autobuilder failures for this
   package can be reported directly to this developer.

 - arch/Config.in.<arch> files are recognized as "the developer is
   looking after the <arch> architecture". In this case, get-developer
   parses the arch/Config.in.<arch> to get the list of possible BR2_ARCH
   values. This way, autobuilder failures for this package can be
   reported directly to this developer.

 - pkg/pkg-<infra>.mk are recognized as "the developer is looking after
   the <infra> package infrastructure. In this case, any patch that adds
   or touches a .mk file that uses this infrastructure will be sent to
   this developer.

gcc: switch to gcc 5.x as the default

gcc 4.9.4 was the last release of the 4.9.x branch, and the gcc
developes will now only be maintaining gcc 5.x and 6.x:

5.x for a while, so the vast majority of the problems should have

package/nvidia-driver: update version

This new version brings in support for egl-wayland, the EGL extensions
aimed at making it possible to implement Wayland servers and clients. As
such, nvidia-driver becomes the second EGL implementation in Buildroot
that can act as a libegl provider with egl-wayland extensions.

In this version, it becomes possible to use our kernel-module infra,
with just a little few minor tricks: we need just specify the Linux
source and build trees (they are the same for us) and the list of
modules to build. We still need a little patch against the Kbuild files.

We also get rid of the LIBS_NO_VERSION trick and always use complete
filenames, as more libs are now packaged with different version in their
filenames, and even some with no version at all.

When installing libs, we switch from a shell loop to a make foreach
loop, which is easier to handle. It has the side-effect (and advantage)
of displaying the install commands for each library, rather than a
single biggish one, so it is easier to see what goes wrong. This also
means that an error in each phase of the install (the copy of the files
then each symlink) can be caught more easily (it was not previously):
each sequence is now its own make command; we need not use "|| exit 1"
after each command, even in a if block, because the if blocks returns
with the exit code of the last command in it; e.g. if an ln fails, the
if-block in which it is enclosed will return the exit code of ln, and
make will catch it.

Similarly for the X driver modules and each of the programs installed:
we now can catch any failure in the isntall of those.

All of this somewhat simplifies the .mk. It is a little bit longer, but
the structure is saner and more explicit.

supertuxkart: Constrain to x86 architecture

Our build system has detected that angelscript can't be
cross-compiled properly. This has been also reported to
supertuxkart [1], and although the developers were open
to take patches fixing STK embedded angelscript, it was
pointed out that non-x86 architectures were not officially
supported and of little interest [2].

Hence, let's constrain the package selection and the host
architecture to x86.

linux: use INSTALL_MOD_STRIP=1 to strip modules

We used to do a special handling of Linux kernel modules when stripping
target binaries because there's some special precious data in modules
that we must keep for them to properly operate. This is for example true
for stack unwinding data etc.

It turned out there're cases when our existing "strip --strip-unneeded"
doesn't work well. For example this removes .debug_frame section used by
Linux on ARC for stack unwinding, refer to [1] and [2] for more details.

Now Linux kernel may strip modules as a part of "modules_install" target
if INSTALL_MOD_STRIP=1 is passed in command line. And so we'll do
allowing kernel decide how to strip modules in the best way.

Still note as of today Linux kernel strips modules uniformly for all
arches with "strip" command, so this commit alone doesn't solve
mentioned problem but it opens a possibility to add later a patch to the
kernel which will strip modules for ARC differently - and that's our
plan for mainline kernel.

util-linux: add -lcurses to LIBS when static linking

When linking statically with -lreadline we also need to specify
-lcurses. We were already passing LIBS=-intl to fix gettext related
issues, so we refactor how LIBS is passed so that several values can be
passed.

It is worth mentioning that:

 1. Passing LIBS= at configure time is not sufficient, because the
    configure script does LIBS="" at its end. So in order for the LIBS
    value to also be effective during the build, it needs to be passed
    in MAKE_OPTS as well.

 2. LIBS=-lintl was only passed at build time (it was not needed for any
    of the configure tests). However, LIBS=-lncurses is needed both at
    configure time (for configure tests) and at build time. Therefore,
    the new variable UTIL_LINUX_LIBS gets passed as the LIBS value at
    both configure time and build time.

package/kvm-unit-tests: new package

The unit tests are tiny guest operating systems that generally execute
only tens of lines of C and assembler test code in order to obtain its
PASS/FAIL result. Unit tests provide KVM and virt hardware functional
testing by targeting the features through minimal implementations of
their use per the hardware specification. The simplicity of unit tests
make them easy to verify they are correct, easy to maintain, and easy
to use in timing measurements. Unit tests are also often used for
quick and dirty bug reproducers. The reproducers may then be kept as
regression tests. It's strongly encouraged that patches implementing

toolchain/wrapper: extend paranoid check to -isystem

Some packages, like libbsd, use -isystem flags to provide so-called
overrides to the system include files. In this particular case, this
is used in a .pc file, then used by antoher package; pkgconf does not
mangle this path; and eventually that other package ends up using
/usr/include/bsd to search for headers.

Our current toolchain wrapper is limited to looking for -I and -L, so
the paranoid check does not kick in.

Furthermore, as noticed by Arnout, there might be a bunch of other
so-unsafe options: -isysroot, -imultilib, -iquote, -idirafter, -iprefix,
-iwithprefix, -iwithprefixbefore; even -B and --sysroot are unsafe.

Extend the paranoid check to be able to check any arbitrary number of
potentially unsafe options:

  - add a list of options to check for, each with their length,
  - iterate over this list until we find a matching unsafe option.

Compared to previously, the list of options include -I and -L (which we
already had) extended with -idirafter, -iquote and -isystem, but leaving
all the others noticed by Arnout away, until we have a reason for
handling them.

toolchain/wrapper: display options leading to a paranoid failure

Current, we only display the path that causes the paranoid failure. This
is sufficient, as we can fail only for -I and -L options, and it is thus
easy to infer from the path, which option is the culprit.

However, we're soon to add a new test for the -isystem option, and then
when a failure occurs, we would not know whether it was because of -I or
-isystem. Being able to differentiate both can be hugely useful to
track down the root cause for the unsafe path.

Add two new arguments to the check_unsafe_path() function: one with the
current-or-previous argument, one to specify whether it has the path in
it or not. Print that in the error message, instead of just the path.

package/systemd: fix build with old toolchains

Toolchains using glibc-2.18 or older do not define O_TMPFILE, which

systemd has a definition for O_TMPFILE if it is missing, but only
