Not necessarily, just maybe.
We do that thing with libgcc_eh.a (unwinder is in libgcc_eh.a and libgcc_s.so.1
and not in libgcc.a).
Or put it in libgcc_eh.a and libgcc_s.so.1?
It is not unwinder, but shares the central registry property with it.

Either that, or do something like cp/g++spec.cc does with shared_libgcc.
Whatever works.
