The current trunk should be correct, there are no explicit calls to the
arch command left, all go through the configure replacement magic.
To test if everything is correct now someone should test the following
scenarios:
* Build --enable-framework --enable-universalsdk on 10.4
* Build --enable-framework --enable-universalsdk on 10.5
* Build --enable-framework --enable-universalsdk --with-universal-
archs=all on 10.5
I cannot test the first one, and will test the last one (which is the
one I'm most interested in).
