Autoconf macros can also be used for portability.

Since it's in a header you can use a simple
#ifndef HAVE_FFSLL
static inline int ffsll(long long value)
{
if (value & 0xFFFFFFFFLL)
return ffs ((int)value);
else
return 32 + ffs ((int)(value >> 32));
}
#endif

You can change all the map_is_anonymous_ code to use malloc/free instead.
> gold/object.cc uses memmem, which is undefined
Could be added to libiberty:
