Subject: [PATCH] asan: fix missing include of signal.h
This breaks when building gcc 4.9.4 / 5.4.0 with
target_platform=powerpc-unknown-linux-gnu with glibc 2.25:
../../../../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 has been verified to apply to at least 4.9.4 and up to 5.4,
the code has been reworked for gcc 6.
