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