[PATCH] mmap64: fix undef warnings

[Mike Frysinger]

The only target that defines this is m68k, so move the existing fallback
define up to avoid warnings on other systems.

2015-07-29  Mike Frysinger  <vapier@gentoo.org>

	* sysdeps/unix/sysv/linux/mmap64.c: Move MMAP2_PAGE_SHIFT define
	before first use.
