What if one calls it with:  brmake -C /path/to/my/O-dir

But as much as we try to 'fix' it, we always uncover corner cases,
becausze the above would consider ${PWD} to be the output dir if
/path/to/my/O-dir is not already configured... :-/

Corner cases after corner cases, I think I'd just try to catch the
obvious and trivial, and leave out the weird cases.

So, either there is a .config in the CWD, or we abort. Deal? ;-)
