Do you mean that ${MACHINE_ARCH} should be changed to "mipseb"/"mipsle",
but directory names should be remained as "XXX/arch/mips", right ?

It doesn't mean that future NetBSD release does support little-endian
powerpc.
If mips should be changed, powerpc should be changed, too.
There are no official release of powerpc NetBSD, so it is relatively
easier than mips.
