I guess we could issue a warning when a static library is used multiple
times. Of course, there are static libraries that are created explicitly
for that purpose, so we would either need a way to avoid these (a
whitelist of libs that are allowed to be linked with multiple times) or
limit this to static libraries from external projects (e.g., doing a
"registration" in gb_StaticLibrary_use_unpacked).
