i'd rather we used the `GNU' cross-compile install targets as-is, as they
basically work the right way and all the tools support this already.  that
is, given ``--target=xx-yy'', we have:

	$prefix/bin/xx-yy-$PROG
	$prefix/lib/gcc-lib/xx-yy
	$prefix/xx-yy/bin/$PROG
	$prefix/xx-yy/include

etc..


i imagine that this can be made to work really well with pkgsrc!
