Provides defines used to determine whether glibc obstacks are
compatible.  Generally speaking, 32-bit targets won't need to use
obstack.o from libiberty if glibc is used, while 64-bit targets will,
until glibc gets the new obstack code.

	* configure.ac: Check size of size_t.
	* configure: Regenerate.
