Fix ARM posix_fadvise64 namespace (bug 17793).

ARM posix_fadvise calls __posix_fadvise64_l64, to which
posix_fadvise64 is a strong alias, but posix_fadvise is a POSIX
function and posix_fadvise64 isn't.  This patch changes it into a weak
alias.

Tested for ARM that this fixes the corresponding linknamespace test
failures.

	[BZ #17793]
	* sysdeps/unix/sysv/linux/arm/posix_fadvise64.c (posix_fadvise64):
	Define as weak alias not strong alias.
