Patch courtesy Phil Blundell:

A couple of improvements for glibc:
	- import Nico Pitre's optimised memcpy routines (roughly doubles memcpy performance on pxa250)
	- fix longlong.h to use smull/umull/clz on machines that have them
	- avoid setting CPPFLAGS when calling configure, since setting it can negate the effect of --with-headers
	- avoid waitpid lossage by filtering out any definition of this syscall from unistd.h
