I think Cobalt switched to n32/n64 recently?  The Alchemy CPUs are
only 32-bit, so they're limited to the o32 ABI (the only ABI that is
completely 32-bit).

I still haven't had a chance to play with the merged 64-bit mips code,
but I'd try an evbmips toolchain first.  That said, some of the evbmips
boards can take 64-bit CPUs (eg malta) while some can't.  I don't know
yet how this is handled!

Cheers,
Simon.
