_Unwind_GetIP as a hidden symbol in libgcc.a is not the problem. If you
built libstdc++.so linked against libgcc_s.so, then when linking using
libstdc++.so you need to have libgcc_s.so available, and, importantly,
libgcc_s.so must be linked before libgcc.a if both are specified.
If you built libstdc++.so only linked against libgcc.a, then you can use
libstdc++.so like that too.
