Actually, that's just failing because config.{guess,sub} is old and doesn't
know about those arches.  If that's fixed it should build on them just fine.

The only thing that is really linux-specific is the kernel drivers, and we
only supply a source package for those, people build the binaries with m-a.

It's known to work on BSD, there have been several ports of the kernel
drivers for that over the years.  And probably could be ported to HURD too
if someone was actually interested in that.

There's no fundamental reason the binary packages aren't arch any, just
practical realities like s390 not having a PCI bus, which is what Phil was
looking at tidying up.  It looks like that might be more pain than gain until
we have a better way to describe those sort of exceptions though ...
