Re-recommit: Add support for the new mips-mti-linux toolchain.

Last time, this caused two Windows buildbots and a single ARM buildbot to fail.
I XFAIL'd the failing test on win32,win64 machines in order to see if the ARM
buildbot complains again.

+// FIXME: Using --sysroot with this toolchain/triple isn't supported. We use
+//        it here to test that we are producing the correct paths/flags.
+//        Ideally, we'd like to have an --llvm-toolchain option similar to
+//        the --gcc-toolchain one.
