Comment (by tdammers):

 OK, I managed to build it, and get some proper test failures:

 {{{
 Unexpected failures:
    /tmp/ghctest-tmsk6xdn/test
 spaces/./simplCore/should_compile/T3234.run  T3234 [stderr mismatch]
 (optasm)

 Unexpected stat failures:
    /tmp/ghctest-tmsk6xdn/test   spaces/./perf/compiler/T5321Fun.run
 T5321Fun [stat not good enough] (normal)
    /tmp/ghctest-tmsk6xdn/test   spaces/./perf/compiler/T5631.run     T5631
 [stat not good enough] (normal)
 }}}

 So I'll look into those.

 On a side note, Haddock now fails to compile, which can be worked around
 by setting `HADDOCK_DOCS=NO` in `mk/validate.mk`, but should, I think, be
 resolved before we can merge.
