That doesn't work in some setups; that's why we have what we have now.
The problem is that this test would actually evaluate to "not equal" and
the prep_buildtree would run on top of the source tree. Ugh.
Another way to find out if you're in the source tree might be to use
something like
test -f configure
but that's of course less than 100% positive. Ian, you seem to use this a
lot; any ideas?
