[sr #110660] AC_LANG_INT_SAVE (used by AC_CHECK_SIZEOF) includes stdlib.h without checking whether it actually exists

Follow-up Comment #3:
> This fails if stdlib.h doesn't actually exist.
Yes, and that's documented behavior. The Autoconf manual says:
> If your program needs to be portable to a _freestanding_

It'd be nice if Autoconf also worked for freestanding programs too. That'd
require a bit of work though. In the meantime I'll mark this as a wishlist
