    update CFLAGS for armv7
    
    This updates $CFLAGS used for armv7. Most of them were just added
    to be consistent with what u-boot does. The important ones here
    are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions).
    
    I removed the hard float support because it got errors and
    coreboot should never use floats anyway. We're still having trouble
    with enums but I want to see how far it gets with this patch.
