shared libobjc & multilibs ?

But most of the hooks one needs to build a shared library can be found in
libiberty.  In particular the code to set up and build both static and sharable
versions of each .o file for each multilib.

You are correct.  multilibs are for dealing with processor variants.  If you
want to build shared libraries, you would basically need to build one for each
already existing multilib.

It's going to need a little work -- it's not going to "just work".

You'll have to look at it for some of the changes, but I strongly recommend 
also
reviewing libiberty.
