Subject: [PATCH] asan: fix missing include of signal.h

This breaks when building gcc 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 applies only to gcc-5-branch, the code has been reworked for gcc 6.
