branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
This is a workaround for the following ld issue exhibited by --gc-sections
option, until a proper fix for binutils is ready:
ld: BFD (GNU Binutils) 2.22 internal error, aborting at elf32-xtensa.c line 3374 in elf_xtensa_finish_dynamic_sections
Fixes:
