   BTW, we just need to make sure everything exported from the shared
   libgcc is also exported from libc.so. I think we will be safe then.

That would be an incredibly stupid thing to do, since it means that
you'd have to recompile glibc whenever things are added to libgcc.so.

You'll probably have to install a libgcc.so linker script in the same
directory as libgcc.a, and preferably create a libgcc_nonshared.a
there too.  Of course this can be postponed until you actually add
new stuff to libgcc.so.
