    Rework the CPU Makefile for GCC 4.7, too.
    
    Due to the previous version's passing of unknown CPUTYPEs just
    through to -march, a buildworld with for example CPUTYPE=haswell
    (which is known by 5.3.0 but not by 4.7.4) would fail for files
    that are compiled with gcc47 in the buildworld.
