10# the same MACHINE_ARCH can run each other's binaries, so it necessarily
11# has word size and endian swizzled in.  However, support files for
12# these machines often are shared amongst all combinations of size
13# and/or endian.  This is called MACHINE_CPU in NetBSD, but that's used
14# for something different in FreeBSD.
