this fails building the native gcc, which requires a bunch of host
tools to run. going on your following post, there is a problem
with genmatch. i don't have access to any osx to test, so i'm not
sure where to start looking. there aren't too many rules used in
the creation of "genmatch" binary - can you run "make cleandir"
in usr.bin/backend/ and then "make MAKEVERBOSE=2 genmatch", and
post all the commands run? there probably will be a configure
run in here, and perhaps the output of it also matters.
