This flag doesn't work with clang (at least with 5.0.0), so needs to
be:

	if cc.has_argument('-fno-prefetch-loop-arrays')
	       cflags += '-fno-prefetch-loop-arrays'
	endif

I'm also getting errors with gcc builds due to maybe-uninitialized
variables, so I also had to add:

	if cc.has_argument('-Wno-maybe-uninitialized')
	       cflags += '-Wno-maybe-uninitialized'
	endif
