Let me be more precise.  Some of the new components
have GPL copyrights.  Many of the components which are
relatively minor modifications of existing files retain the current
copyrights and could be checked in.  It might be possible to
support ELF linking without the full package.  It might also
be possible that the GPL portions of the code are not needed
or could be segregated into packages away from libc.

There are several things that are not supported, but the core
pieces needed to provide support (and support further
development) are there.  In particular, some of the really
hard pieces (like the ELF stub / crt0) are working and
retain the original copyrights.

I don't have a personal need for this, but it is interesting
and worth discussing.
