Configury changes for obstack optimization
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.
libiberty/
* configure.ac: Get size of size_t.
* config.in: Regenerate.
* configure: Regenerate.
