X11: Link libgcc statically with use_static_cpp option 

We were already linking libstdc++ statically for official binaries,
protecting us against most portability issues. But apparently since
we started using GCC 7 for official builds, we also need to link
libgcc statically for at least 32-bit builds to be portable.

Fixes #16409.
