Change Details

This program links against a shared libgcc_s.so (which will be instrumented if WITH_ASAN is set). I'm not sure if this program should be linked against libgcc_s.so at all, but for now I've chosen the least invasive change to allow building world with sanitizers.

The userboot/test program links against the default userspace libraries (e.g. shared libgcc_s.so) that will be instrumented if WITH_ASAN is set. All other programs link against libsa instead of libc and therefore can't use the sanitizer runtime library. To fix the stand/ build with sanitizers, we disable MK_ASAN/MK_UBSAN if -nostdlib is found in the LDFLAGS (i.e. we are using libsa instead of libc).
