gcc: add support for gcc 5.1
This commit adds support for gcc 5.1 in Buildroot. In terms of gcc
patches, compared to gcc 4.9.x:
* Kept as is, sometimes after minor adjusments:
100-uclibc-conf.patch
301-missing-execinfo_h.patch
810-arm-softfloat-libgcc.patch
830-arm_unbreak_armv4t.patch
840-microblaze-enable-dwarf-eh-support.patch
850-libstdcxx-uclibc-c99.patch
860-cilk-wchar.patch
* Dropped:
110-pr64896.patch
111-pr65730.patch
* Split in multiple parts:
900-musl-support.patch
The patches from Crosstool-NG for muls support are used instead of
one single patch.
* Renamed:
910-gcc-poison-system-directories.patch to
200-gcc-poison-system-directories.patch
920-libgcc-remove-unistd-header.patch to
201-libgcc-remove-unistd-header.patch
Since the 9xx part of the series is now used by the various musl
related patches.
We have tested the following configurations, with a minimal Busybox
system:
* ARM, uClibc-ng
* ARM, glibc
* ARM, musl
* x86, uClibc-ng and uClibc 0.9.33.2
* x86, glibc
* x86, musl
All of the configurations built fine. All the configurations boot fine
in Qemu, except x86/uClibc (either ng or 0.9.33.2), it segfaults when
running init:
devtmpfs: mounted
Freeing unused kernel memory: 300K (c1389000 - c13d4000)
init[1]: segfault at 0 ip b77708c1 sp bfa9bb0c error 4 in ld-uClibc-0.9.33.2.so[b776c000+6000]
Kernel panic - not syncing: Attempted to kill init! exitcode=0x0000000b
We'll give some time for the uClibc developers to fix the problem
before taking other measures in Buildroot to exclude gcc 5.1 from a
x86/uClibc configuration.

gcc: use BR2_EXTRA_GCC_CONFIG_OPTIONS in gcc-initial and gcc-intermediate
When refactoring the internal toolchain backend logic, the code was
changed to pass the custom configure options given through
BR2_EXTRA_GCC_CONFIG_OPTIONS only for the gcc final pass, with the
idea that we're only interested by user customization for the final
compiler.
However, the beaglebone_defconfig was passing --with-float=hard
--with-fpu=vfpv3-d16 as BR2_EXTRA_GCC_CONFIG_OPTIONS, and since the
refactoring, it was causing build failures of the beaglebone_defconfig
(with messages saying that Busybox is built to use VFP arguments, but
libc/libm are not). This is due to the fact that the gcc intermediate,
which is used to build the C library, wasn't built to generate hard
float, while the final compiler was generating hard float.
So, we get back to the original situation where the options in
BR2_EXTRA_GCC_CONFIG_OPTIONS are passed to all of the compiler
passes. Of course, the specific case of hard float will be fixed by
following patches in this area, but the idea still remains: the three
gcc should have the same options, if those options affected the ABI of
the generated code.
