Assuming that it supports the architectures we need well, which at the
present time it isn't clear that it will...

: on this direction at all, which is disappointing.

The problem is that it really isn't a terribly viable solution, so why
waste a bunch of time on it?  Does the build-world stop in the middle
and rebuild stuff?  Right now we have finely matched libraries and
compilers, how does one address that problem with the compiler out in
the ports?  You'll need a matched set of binutils as well (well,
matched meaning known compatible here), and the build system has a
strong bias towards the compiler knowing which ones to use..  These
problems can all be surmounted, but it just feels like a big kludge.

Agreed.  I'll likely be working in this area soon.  Last time I tried,
it was possible, but very difficult and error-prone to do it by
