Subject: [PATCH] Disable quickcheck tests on mips

Two reasons:
    * the C versions __divti3 and __modti3 are apparently broken,
      at least when used in quickcheck. They change their own arguments.
    * compiler_rt's support for mips is disabled already on clang [1].
      Its desireable to support working "cargo test" on that compiler
      as well, and not greet the tester with linker errors.
