dropbear: fix build with non-SSP capable toolchain

By default, Dropbear's configure script enables hardening
flags. Unfortunately, the check for SSP only uses AC_COMPILE_IFELSE(),
and therefore doesn't properly test for the availability of libssp,
visible only at link time.

In addition, Buildroot passes its own hardening flags, depending on
various global options. So, we simply disable hardening flags in
Dropbear.

This fixes a build failure with non-SSP capable toolchains happening
since the bump to 2018.76.

qemu: disable qemu user emulation on MIPS64 for host variant

According to target/mips/TODO in the Qemu sources:

MIPS64
------
- Userland emulation (both n32 and n64) not functional.

And indeed, trying to run a mips64n32 binary under qemu user emulation
results in:

Invalid ELF image for this architecture

So we move the BR2_mips64(el) dependency from
BR2_PACKAGE_HOST_QEMU_ARCH_SUPPORTS to
BR2_PACKAGE_HOST_QEMU_SYSTEM_ARCH_SUPPORTS, so that only the system
emulation is available on mips64, and not the user-mode emulation.

qemu: introduce BR2_PACKAGE_HOST_QEMU_{SYSTEM, USER}_ARCH_SUPPORTS

Not all architectures are supported by both the system emulation and
user-mode emulation in Qemu, so a single
BR2_PACKAGE_HOST_QEMU_ARCH_SUPPORTS doesn't work very well.

Therefore, this commit introduces the
BR2_PACKAGE_HOST_QEMU_{SYSTEM,USER}_ARCH_SUPPORTS hidden options. We
keep the BR2_PACKAGE_HOST_QEMU_ARCH_SUPPORTS option for the (numerous)
architectures supported by both system emulation and user-mode
emulation.

The 'select' logic to make sure that at least either system emulation
or user-mode emulation is selected is reworked, and done carefully to
avoid recursive Kconfig dependencies.

For now BR2_PACKAGE_HOST_QEMU_SYSTEM_ARCH_SUPPORTS and
BR2_PACKAGE_HOST_QEMU_USER_ARCH_SUPPORTS are the same, but they will
become different in a follow-up commit.

linux-tools: perf: add option to build TUI

Since Linux 3.10, perf's NO_NEWT configuration option simply sets
NO_SLANG=1 and there is no dependency on libnewt.

We already handle NO_SLANG correctly based on whether or not
BR2_PACKAGE_SLANG is selected, so all we accomplish by setting NO_NEWT=1
is disabling perf's TUI when all of the dependencies are available.

To simplify all of this, introduce a new config option to enable the
perf TUI which depends on slang and add a check to prevent building the
TUI on versions which are too old.  The check for NO_SLANG is equivalent
to checking if NO_NEWT is required as NO_SLANG was added in the same
commit that removed the libnewt dependency and deprecated NO_NEWT
(6692c262df4f, "perf tools: Remove dependency on libnewt", 2013-03-28).

abootimg: new package

This tool might be useful on Android devices modded with Buildroot. Indeed
it allows to modify Android Boot Image partition directly from running

(mainly bootloader) while testing/using Buildroot kernel/rootfs.

For example, one can modify kernel cmdline on Boot Image partition and
tell Android bootloader to launch kernel with a given rootfs fitted with BR
instead of Android's one.

package/clang: new package

This patch provides Clang tools and libraries for the host and
libclang for the target.

host-clang is needed to build libclc, which is provided in a follow-up

We need libclang for the target because it is used by most of OpenCL
implementations.

A later patch in this series will enable Clover, the OpenCL
implementation part of Mesa3D, which requires libclang.

clang-tblgen must be copied to HOST_DIR as it is not installed by
default but is needed for cross-compilation:

package/flann: fix build with cmake >= 3.11

CMake < 3.11 doesn't support add_library() without any source file
(i.e add_library(foo SHARED)). But flann CMake use a trick that use
an empty string "" as source list (i.e add_library(foo SHARED "")).
This look like a bug in CMake < 3.11.

With CMake >= 3.11, the new behaviour of add_library() break the
existing flann CMake code.

>From CMake Changelog [1]:
"add_library() and add_executable() commands can now be called without
 any sources and will not complain as long as sources are added later
 via the target_sources() command."

Note: flann CMake code doesn't use target_sources() since no source file
are provided intentionally since the flann shared library is created by
linking with the flann_cpp_s static library with this line:

target_link_libraries(flann_cpp -Wl,-whole-archive flann_cpp_s -Wl,-no-whole-archive)

If you try to use "add_library(flann_cpp SHARED ${CPP_SOURCES})" (as it should
be normally done), the link fail due to already defined symbol.

They are building the shared version using the static library "to speedup the
build time" [3]

This issue is already reported upstream [2] with a proposed solution.

boot/uboot: default to kconfig buildsystem for latest version

By default, the builsystem for uboot defaults to 'legacy', while the
default version is very well capable of using the 'kconfig' buildsystem
instead.

Having the 'legacy' buildsystem be the default in that case makes it
quite inconvenient for users: they would expect to be able to use e.g.
uboot-menuconfig et al. with the default uboot version.

Switch to using 'kconfig' when we use the latest version. Keep the
'legacy' as default for everything else.

Also, invert the 'legacy' and 'kconfig' entries in the choice: it is
nicer to have the recent and future-proof entry first.

download/git: fix transform regexp for older tar versions

Older versions of tar (e.g. 1.27.1) incorrectly interpret the escaping
of the regexp separator, and generate broken tarballs.

For example, given the following transform expression:
    --transform="s/^\.\//squashfs-e38956b92f738518c29734399629e7cdb33072d3\//"

the resulting paths in the generated tarball would be:
    squashfs-e38956b92f738518c29734399629e7cdb33072d3\/

i.e. a directory which last character is indeed a '\'.

We fix that by using a separator which is very unlikely to occur in a
filename.

Fixes:

lz4: improve static only build support

The current method of supporting static only build, removal of all lines
that match the SHARED regex from lib/Makefile, is crude and fragile.
Instead, patch lib/Makefile to allow disable of shared libraries.

grub2: force -fno-stack-protector in CPPFLAGS

In commit 2a27294e9ade6130a12ced9a1f152c51431a870e ("grub2: force
-fno-stack-protector in CFLAGS"), a fix was made to the grub2 package
to make it build properly even when SSP support is enabled.

However, commit 20a4583ebf7fe97ea22a1ea11621dd44a8114ca5 ("security
hardening: add RELFO, FORTIFY options") reworked how SSP options are
passed, and they are now passed in CPPFLAGS instead of CFLAGS, making
the fix introduced by 2a27294e9ade6130a12ced9a1f152c51431a870e no
longer operating.

This commit will force no-stack-protector in CPPFLAGS instead of
CFLAGS.

support/testing: add test for syslog-ng

Check:
 - the daemon is started;
 - a message is collected;
 - the daemon does not issue a warning message on startup.

When the .conf file version does not match the package version a warning
message shows up on serial on every boot. This message is generated by
syslog-ng before it is running, so it is not logged to
/var/log/messages. So in order to test the message is generated, restart
the server. It makes the message appears on /var/log/messages (since the
server is already running) where its existence can be easily tested
using grep.

download/git: be sure we do fetch something

The different versions of git will behave in different ways when
fetching remote references, as summarised by the table below:

              |     ancient git         | new git
--------------------------------------------------------------------
git fetch     | fetch all refs but tags | fetches all refs but tags
git fetch -t  | fetches only tags       | fetch all refs and tags

(git-fetch may still fetch tags, but only if reachable from a branch)

So, to cover all the bases, we do a simple fetch, to be sure we have
branches, followed by the existing fetch -t, to get extra tags.

toolchain-external-custom: allow specifying relative path to binaries

There are cases where a downloaded toolchain doesn't have its binaries
placed directly in a "bin" subfolder (where BuildRoot currently looks
for them).

A common example is the official Raspberry Pi Toolchain
(https://github.com/raspberrypi/tools), which has its binaries in
"arm-bcm2708/arm-linux-gnueabihf/bin".

This commit introduces BR2_TOOLCHAIN_EXTERNAL_REL_BIN_PATH that defaults
to "bin" and can be changed as needed.
