c++: Local symbols do not get module manglings
Internal-linkage entity mangling is entirely implementation defined --
there's no ABI issue. Let's not mangle in any module attachment to
them, it makes the symbols unnecessarily longer.
gcc/cp/
* mangle.cc (maybe_write_module): Check external linkage.
gcc/testsuite/
* g++.dg/modules/mod-sym-4.C: New.
