[PATCH] Remove unnecessary prototypes for __builtin functions

[Jakub Jelinek]

Hi!

This has been apparently workaround for some GCC bug, but I've verified
that it makes no difference at all on .plt slots with GCC 4.1, 4.3 and 4.4.

In 4.4, we are considering disallowing redefinition of __builtin_*
functions, so glibc wouldn't compile at all because of this.

	* include/stdio.h (__builtin_fwrite, __builtin_fwrite_unlocked):
	Remove.
