    powerpc: Drop old workaround for old gcc
    Very old versions of gcc defined _BIG_ENDIAN and _LITTLE_ENDIAN. So to
    work around that, we undefined them here. However, that causes problems
    for programs that do:
    (and many other variations on that theme). Since this often is the
    result of weirdly nested includes in the ports world that are hard to
    unwind, drop this workaround to help more ports build out of the box.
    If there's still an issue here (and my testing hasn't shown it), we'll
    fix the issue in a brand-new way once I have a reproducer.
    This fixes the mesa-devel build, and others
