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
causes build failures on some archs.

systemd has a definition for O_TMPFILE if it is missing, but only
defines it for i386 or x86_64. Furthermore, the header defining it is
not included everywhere O_TMPFILE is used.

Fix that with three patches backported from upstream:
  - include the needed header where it is needed (he!),
  - define O_TMPFILE for all archs, according to linux-4.8rc3,
  - no longer guard against undefined O_TMPFILE in fileio.

toolchain: Bump ARC tools to arc-2016.09-eng013

As described at:
4520524ba055706236db9f00dd79f1b2e2e87fde
this commit continues a series of updates of ARC tools.
This time we're updating tools to arc-2016.09-eng013.

This engenering build contains some important GCC updatesthat fixes
some failures for ARC, such as:
http://autobuild.buildroot.net/results/f80/f80ad8a07d9d58b46592c2c99b227197b0f808d3//

http://autobuild.buildroot.net/results/521/52157aa2b5d75b5338f3bde7ae5beb3d300283d3//

We still keep GDB as it is of arc-2016.03 release because there're some
issues we'd like to resolve before releasing it to wider audience.

So again note this is next engineering builds of arc-2016.09 series
and it might have all kinds of breakages, please don't use it for
production builds.

core: distclean is a noconfig target

When the .config contains invalid configuration *(e.g. two providers for
a same virtual package), it is not possible to run "make distclean"
because the .config file is sourced and packages interpreted in this
case.

Add distclean to the noconfig list, so that we can run it in all cases.

However, this meand that DL_DIR is no longer set, and thus the default
download location never removed. We fix that by always removing the
download location, so that if it is the one configured we still remove
it (no change) and if it is not the one configured, we remove an
non-existing location and leave the user's location intact (no change
either).

core: don't build host-cmake if it is available on the build host

Currently all cmake packages depend on host-cmake. Unfortunately
host-cmake takes a long time to configure and build: almost 7 minutes
on a dual-core i5 with SSD. The time does not change even with ccache
enabled.

Indeed, building host-cmake is avoidable if it is already installed on
the build host: CMake is supposed to be quite portable, and the only
patch in Buildroot for the CMake package seems to only affect
target-cmake.

Thus we automatically skip building host-cmake and use the one on the
system if:
 - cmake is available on the system and
 - it is recent enough.

First, we leverage the existing infrastructure in
support/dependencies/dependencies.mk to find out whether there's a
suitable cmake executable on the system. Its path can be passed in the
BR2_CMAKE environment variable, otherwise it defaults to "cmake". If
it is enabled, found and suitable then we set BR2_CMAKE_HOST_DEPENDENCY
to empty; otherwise we set BR2_CMAKE_HOST_DEPENDENCY to 'host-cmake' and
override BR2_CMAKE with "$(HOST_DIR)/usr/bin/cmake" to revert to using
our own cmake (the old behaviour).

Then in pkg-cmake.mk we replace the hard-coded dependency on host-cmake
to using the BR2_CMAKE_HOST_DEPENDENCY variable, and we use $(BR2_CMAKE)
instead of $(HOST_DIR)/usr/bin/cmake.

Unlike what we do for host-tar and host-xzcat, for host-cmake we do
not add host-cmake to DEPENDENCIES_HOST_PREREQ. If we did, host-cmake
would be a dependency for _any_ package when it's not installed on the
host, even when no cmake package is selected.

Cmake versions older than 3.0 are affected by the bug described and
fixed in Buildroot in ef2c1970e4bf ("cmake: add patch to fix Qt mkspecs
detection"). The bug was fixed in upstream CMake in version 3.0 [0].

Amongst all the cmake packages currently in Buildroot, the currently
highest version mentioned in cmake_minimum_required() is 3.1 (grantlee
and opencv3).

Thus we use 3.1 as the lowest required cmake for now, until a package is
bumped, or a new package added, with a higher required version.

pkg-kconfig: support alternative .config location

Kconfig clones, such as openconf used by xvisor [1], do not look for
.config at the root of the build directory, but in a subdirectory (e.g.
build/openconf).

This patch introduces a new Makefile variable named
$(2)_KCONFIG_DOTCONFIG, which contains the path to .config relative to
the source directory of the package. It defaults to .config and can be
overridden in the package Makefile.

It also creates the full directory hierarchy where the .config file is
stored, in case it does not exist (e.g. in xvisor).

This allows the use of the kconfig-package infrastructure with packages

infra/pkg-kconfig: Be sure to reconfigure the package on foo-reconfigure

Currently, calling foo-reconfigure for a kconfig-based package will not
re-trigger the configuration (kconfig-wise) step for the package.

This can be problematic when using an override-srcdir suring development
and the content of the veride-srcdir changes (e.g. on a rebase, a merge,
or during a bisect).

This is because the configuration (kconfig-wise) of the package is not
done in the _CONFIGURE_CMDS block, but as a separate action that is not
part of any step [0].

So, be sure to remove the stamp file .stamp_kconfig_fixup_done during
the foo-clean-for-reconfigure rule, so that the configuration is applied
again with the new source tree.

We use another rule, foo-clean-kconfig-for-reconfigure, because we do
not want to override the default foo-clean-for-reconfigure rule, and we
have no way to add conditional commands to it.

[0] The reasons it was not done are not entirely clear in my head, but
IIRC that was not working at the time we tried with Thomas DS.

toolchain-external: fix potential entire root filesystem removal

This reverts commit a0aa7e0e1750f6ace2879ea8adb1425a41431b79 and reworks
the code to fix a major and potentially catastrophic bug when the
following conditions are met:

 - The user has selected a "known toolchain profile", such as a Linaro
   toolchain, a Sourcery CodeBench toolchain etc. People using "custom
   toolchain profile" are not affected.

 - The user has enabled BR2_TOOLCHAIN_EXTERNAL_PREINSTALLED=y to
   indicate that the toolchain is already locally available (as
   opposed to having Buildroot download and extract the toolchain)

 - The user has left BR2_TOOLCHAIN_EXTERNAL_PATH empty, because his
   toolchain is directly available through the PATH environment
   variable. When BR2_TOOLCHAIN_EXTERNAL_PATH is non-empty, Buildroot
   will do something silly (remove the toolchain contents), but that
   are limited to the toolchain itself.

When such conditions are met, Buildroot will run "rm -rf /*" due to
TOOLCHAIN_EXTERNAL_INSTALL_DIR being empty.

This bug does not exist in 2016.05, and appeared in 2016.08 due to
commit a0aa7e0e1750f6ace2879ea8adb1425a41431b79.

Commit a0aa7e0e1750f6ace2879ea8adb1425a41431b79 removed the assignment
of TOOLCHAIN_EXTERNAL_SOURCE and TOOLCHAIN_EXTERNAL_SITE to empty, as
part of a global cleanup to remove such assignments that supposedly
had become unneeded following a fix of the package infrastructure
(75630eba22b20d6140a5b58a6d1e35598fb3c0d3: core: do not attempt
downloads with no _VERSION set).

However, this causes TOOLCHAIN_EXTERNAL_SOURCE to be non-empty even
for BR2_TOOLCHAIN_EXTERNAL_PREINSTALLED=y configuration, with the
following consequences:

 - Buildroot downloads the toolchain tarball (while we're saying the
   toolchain is already available). Not dramatic, but clearly buggy.

 - Buildroot registers a post-extract hook that moves the toolchain
   from its extract directory (output/build/toolchain-external-.../ to
   its final location in host/opt/ext-toolchain/). Before doing this,
   it removes everything in TOOLCHAIN_EXTERNAL_INSTALL_DIR (which
   should normally be host/opt/ext-toolchain/).

Another mistake that caused the bug is commit
b731dc7bfb9c8ce7be502711f0b44ccab5515f1d ("toolchain-external: make
extraction idempotent"), which introduce the dangerous call "rm -rf
$(var)/*", which can be catastrophic if by mistake $(var) is
empty. Instead, this commit should have just used rm -rf $(var) to
remove the directory instead: it would have failed without consequences
if $(var) is empty, and the directory was anyway already re-created
right after with a mkdir.

To address this problem, we:

 - Revert commit a0aa7e0e1750f6ace2879ea8adb1425a41431b79, so that
   _SOURCE and _SITE are empty in the pre-installed toolchain case.

 - Rework the code to ensure that similar problems will no happen in the
   future, by:

   - Registering the TOOLCHAIN_EXTERNAL_MOVE hook only when
     BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y, since moving the toolchain is
     only needed when Buildroot downloaded the toolchain.

   - Introduce a variable TOOLCHAIN_EXTERNAL_DOWNLOAD_INSTALL_DIR which
     is the path in which Buildroot installs external toolchains when it
     is in charge of downloading/extracting them. Then, the
     TOOLCHAIN_EXTERNAL_MOVE hook is changed to use this variable, which
     is guaranteed to be non-empty.

   - Replace the removal of the directory contents $(var)/* by removing
     the directory itself $(var). The directory was anyway already
     re-created if needed afterwards. Thanks to doing this, if $(var)
     ever becomes empty, we will do "rm -rf" which will fail and abort
     the build, and not the catastrophic "rm -rf /*".

package/libupnpp: add patch to fix build issue

Bumping libupnpp to version 0.15.0 introduced a build error for some
architectures:

```
./libupnpp/workqueue.h:308:29: error: field 'res' has incomplete type
         std::future<void *> res;
                             ^
./libupnpp/workqueue.h: In member function 'bool
WorkQueue<T>::start(int, void* (*)(void*), void*)':
./libupnpp/workqueue.h:81:25: error: invalid use of incomplete type
'class std::packaged_task<void*(void*)>'
             w.res = task.get_future();
```

The problem is that `std::future` is not available for all
architectures, e.g. it is missing for ARMv5 (soft-float). libstdc++
enables `std::future` only if `ATOMIC_INT_LOCK_FREE > 1`, which
according the the libstdc++ documentation means that operations on
atomic ints are guaranteed to be lock-free.

This check is not true for some target, e.g. the toolchain for the
ARMv5 target defines:

```
$ echo | /usr/bin/arm-linux-g++ -dM -E - | grep ATOMIC_INT_LOCK_FREE
#define __GCC_ATOMIC_INT_LOCK_FREE 1

```

We add a patch from upstream which detects if `std::future` is available
and opts-out the functionality for unsupported targets.

board/minnowboard-max: Add kernel options to support USB disks

As reported by bug #9176 the current v4.6 kernel config
(used by Minnowboard MAX and Turbot) does not support
USB disks. Since this is a pretty essential functionality,
it's desirable to have it, so let's add the required options.

Kernel config linux-v3.8.config (currently used by the first
generation Minnowboard) doesn't need this change.

package/libssh2: fix dependency on libgcrypt

Since 2f89476 (package/libgpg-error: bump to version 1.23), libssh2 has
inherited the dependency from libgcrypt (propagated from libgpg-error).

However, since libssh2 can use either openssl or libgcrypt as a backend,
the dependency should be relaxed when openssl is available.

But the test is broken and inverted: it will make libssh unavailable as
soon as openssl is enabled.

Fix this dependenc byt doing what other similar packages do: select
openssl if the other crypto backend (here libgcrypt) is not enabled.
This also allows us to drop the propagated dependency on the arch
condition.

However, since libssh can use either openssl or libgcrypt as a backend,

But the test is broken and inverted: it will make libssh unavailable as

This in itself is already incorrect, but that can cause further issues,
as some packages (e.g. Kodi) will select (indirectly) openssl, and has
an option to select libssh; enabling that option causes unmet direct
dependencies of libssh:

    warning: (BR2_PACKAGE_KODI_LIBSSH) selects BR2_PACKAGE_LIBSSH which
    has unmet direct dependencies (BR2_USE_MMU && !BR2_STATIC_LIBS &&
    BR2_TOOLCHAIN_HAS_THREADS && BR2_PACKAGE_LIBGPG_ERROR_ARCH_SUPPORTS
    && !BR2_PACKAGE_OPENSSL)

Fix this dependency by doing what other similar packages do: select
openssl if the other crypto backend (here libgcrypt) is not enabled.
This also allows us to drop the propagated dependency on the arch
