libgcc cannot be built with glibc 2.27

Project Member Reported by yunlian@chromium.org, Jun 6 2018 
With glibc 2.27, I got the following error when building libgcc.

mv -f .deps/asan_malloc_mac.Tpo .deps/asan_malloc_mac.Plo
/mnt/host/source/src/third_party/../aosp/toolchain/gcc/gcc-4.9/libsanitizer/asan/asan_linux.cc: In function 'bool __asan::AsanInterceptsSignal(int)':

libgcc: disable libsanitizer.

This disables libsanitizer for ligcc because we don't use it and
we cannot build it with glibc 2.27

BUG= chromium:849964 
TEST=emerge-kevin gcc-libs works with glibc 2.27
