Good catch, thanks.

This no longer produces a foo.cmxa, is that deliberate?

Likewise the foo_stubs.a and libfoo_stubs.a.

Can this change be made part of mk-caml-lib-bytecode ? 

I don't much like it but the existing caml build stuff uses that
quiet-command stuff so I think this new command will end up standing out
like a sore thumb. If you want to fix this by nuking all that stuff then
that is fine by me ;-)
