Malloc attribute for posix_memalign is wrong

compiling glibc on x86-64 with GCC 4.1 CVS I get warnings like:
../include/stdlib.h:99: warning: ‘__malloc__’ attribute ignored

The problem is that the malloc attribute is only defined for functions
returning memory, which memalign does only do indirectly.

Ok to submit the appended patch?

	* include/stdlib.h: Remove malloc attribute from __posix_memalign.
	* stdlib/stdlib.h: Likewise.
