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.
