    iwmmxt: Disallow if gcc version is < 4.8.
    
    Later versions of gcc-4.7.x are capable of generating iwMMXt
    instructions properly, but gcc-4.8 contains better support and other
    fixes, including iwMMXt in conjunction with hardfp. The existing 4.5
    requirement was based on attempts to have OLPC use a patched gcc to
    build pixman. Let's just require gcc-4.8.
