make "make TARGET=foo" work correctly. Before, it would fail to set

TARGET_ARCH correctly.  Now it does, even for pc98.  We should suggest
TARGET=foo in preference to TARGET_ARCH because the former is
unambiguous and the latter isn't, so update the docs.

This means that a long standing gripe I've had with this comes to a
close.  I can build pc98 w/o specify both things.  make TARGET=arm
works (rather than trying to build a arm:amd64 image and dying badly
in the attempt).

If you specify only TARGET_ARCH, then you get the old behavior.

# we can likely simplify the UNIVERSE target now to use this, but I'm not
# up for breaking that tonight :-).

# We should consider adding some kind of sanity check for TARGET_ARCH
# and TARGET.
