Programs compiled with gdc (such as tumiki-fighters and torus-trooper) that depend on c++ libraries were failing with errors such as /nix/store/3fqi6nigj8dkbvjnw8y4dy59gkq8vsj4-binutils-2.38/bin/ld: /nix/store/36960p41h83cwkcs2vpzg8ni39w4sc5m-bulletml-0.0.6/lib/libbulletml.so: undefined reference to `std::__throw_bad_array_new_length()@GLIBCXX_3.4.29' because of the mismatch with the gcc version used to compile the libraries. This commit unpins the gcc version gdc is based on, so they are kept in sync. gdc9 was removed since no other package depends specifically on that version
