I've done some testing on the ghc-7.10 branch (with a couple of patches
cherry picked from master) with llvm-3.6 on amd64-linux. WIth this,
there are 17 unexpected failures during validate:

   deriving/should_fail       T7959 [stderr mismatch] (normal)
   deriving/should_fail       drvfail005 [stderr mismatch] (normal)
   deriving/should_fail       drvfail009 [stderr mismatch] (normal)
   indexed-types/should_fail  SimpleFail14 [stderr mismatch] (normal)
   simplCore/should_compile   spec-inline [stderr mismatch] (optasm)
   typecheck/should_compile   T10195 [exit code non-0] (normal)
   typecheck/should_fail      T2994 [stderr mismatch] (normal)
   typecheck/should_fail      T3540 [stderr mismatch] (normal)
   typecheck/should_fail      T7778 [stderr mismatch] (normal)
   typecheck/should_fail      tcfail036 [stderr mismatch] (normal)
   typecheck/should_fail      tcfail057 [stderr mismatch] (normal)
   typecheck/should_fail      tcfail063 [stderr mismatch] (normal)
   typecheck/should_fail      tcfail134 [stderr mismatch] (normal)
   typecheck/should_fail      tcfail146 [stderr mismatch] (normal)
   typecheck/should_fail      tcfail147 [stderr mismatch] (normal)
   typecheck/should_fail      tcfail151 [stderr mismatch] (normal)
   typecheck/should_fail      tcfail209 [stderr mismatch] (normal)

All bit one oft these all seem to be stderr mismatches rather than
actual problems.

My validate run on armhf is still running.
