That sounds like a nice solution, if it works.

But I'm not convinced that it will work in all cases.

In particular if you have a main program that statically links in
libgcc.a and a shared library that statically links in libgcc.a,
and the shared library is dlopen()ed from the main program,
then you can get two copies, I'm pretty sure.
