Building a toolchain for SuperH/musl works, but the toolchain generate
bogus binaries, because the path to the program interpreter is not
known (and therefore is /dev/null).
This commit backports a patch from gcc 6.x to make SuperH support with
musl work properly.
The patch is not needed in gcc >= 6.x because the musl support is
upstream. The patch is not needed for gcc 4.9 because we had a
different musl support patch that had support for all architectures in
one patch.

Add a new patch to allow to build gcc 7.1 without extracting gcc/testsuite
directory.
This new gcc version require a kernel patch [1] to avoid a build issue with
____ilog2_NaN symbol. The following kernel version contain contain already
this patch :
4.11, 4.10.6, 4.9.18, 4.4.57, 3.18.50 and 3.12.73.
To build a toolchain based on gcc 7 and uClibc-ng 1.0.24, the patch [2] is
required to avoid a build issue due to missing aligned_alloc() definition.

mpd package fails for both internal and external ARC toolchain as check
for pthread support fails. Such checks fails because _REENTRANT flag is
not defined in gcc even when -pthread is passed.
So we add patch to gcc that defines _REENTRANT on ARC when -pthread is
passed.
Also it disables mpd package for external ARC toolchain as it fails due
to the same issue.
This patch should be reverted as soon as the patch for GCC becomes a
part of ARC toolchain.

All buildroot included upstream binutils versions are supported.
Gcc support is not upstream, to be able to enable musl C library
support later, we use the branch with musl support.
At the moment it is possible to build a musl based toolchain,
but bootup in Qemu fails.

for gdbserver/gdb on Linux, yet.

gcc 4.7 introduced the sync_8 builtin functions for ARM. For ARM < v7,
this requires calling into the kernel. However, the failure path of
that call reports an error with the __write() function, which is a
glibc internal function. Therefore, it fails to link with uClibc or
musl. This was fixed in gcc 5.2.0, by replacing the __write() with
a plain write().
For sync_8 itself we have solved this with the conditions on
BR2_TOOLCHAIN_ARM_HAS_SYNC_8. However, the same function is also used
for the implementation of atomics.
For the internal toolchain, we can fix this by backporting the patch
to 4.9.4 and 4.8.5.
