libsanitizer in gcc fails to build on PowerPC with gcc versions 4.9
and 5.x used in conjunction with glibc 2.25, with the following error:
../../../../gcc-host/libsanitizer/asan/asan_linux.cc: In function 'bool __asan::AsanInterceptsSignal(int)':
../../../../gcc-host/libsanitizer/asan/asan_linux.cc:222:20: error: 'SIGSEGV' was not declared in this scope
return signum == SIGSEGV && common_flags()->handle_segv;
This commit adds a patch that has been submitted to upstream gcc
(https://patchwork.ozlabs.org/patch/725596/) but not merged. The patch
is no longer needed with gcc 6.x and later because the code has been
reworked.
Fixes Buildroot bug #10061
