Detect but ignore -fdebug-prefix-map on mingw-w64
mingw-w64 is based on GCC, so supports -fdebug-prefix-map, but the test
for it is skipped in configure. The test is no longer skipped (which
means that Config.c_has_debug_prefix_map returns true) but the flag is
still explicitly not used by the compilers (as before).
