It seems there's was still just enough multilib support on the machine to trigger mips64el sanitizers again but having worked around that the parts of lit that aren't mips64el sanitizers are working so far. llvm-lit is still going but big-endian mips and cross compilation was fine so I'm expecting little endian to be ok too. It's showing an ETA of about 90 mins for the remaining tests from clang and llvm at the moment. I'm going to run the MIPS32 sanitizer lit tests after that.

Overall, I think we're probably ready for final. I just can't confirm that rc3 was definitely ok for little endian mips yet.

The LNT test-suite runs were ok with the rc3 build.
