Seemed like a good idea to have current GHC packaged. This almost works,
except for two real test failures (not sure if these are just on my system),
and some more "stat failures". It would be neat if someone could run the
build and see if they get the same failures.

Unexpected results from:
TEST="T5631 T8108 T9203 T9630 haddock.Cabal haddock.base parsing001 posix010"

SUMMARY for test run started at Tue Jul 16 12:47:07 2019 UTC
 2:44:36 spent to go through
    6525 total tests, which gave rise to
   25446 test cases, of which
   18529 were skipped

      41 had missing libraries
    6782 expected passes
      86 expected failures

       0 caused framework failures
       0 caused framework warnings
       0 unexpected passes
       2 unexpected failures
       6 unexpected stat failures

Unexpected failures:
   ../../libraries/unix/tests/T8108.run              T8108 [bad stderr] (normal)
   ../../libraries/unix/tests/libposix/posix010.run  posix010 [bad exit code] (normal)

Unexpected stat failures:
   perf/compiler/T5631.run         T5631 [stat too good] (normal)
   perf/compiler/parsing001.run    parsing001 [stat too good] (normal)
   perf/compiler/T9630.run         T9630 [stat not good enough] (normal)
   perf/haddock/haddock.base.run   haddock.base [stat too good] (normal)
   perf/haddock/haddock.Cabal.run  haddock.Cabal [stat too good] (normal)
   perf/should_run/T9203.run       T9203 [stat too good] (normal)

First failure:

cd "../../libraries/unix/tests/T8108.run" &&  "/tmp/guix-build-ghc-8.6.5.drv-0/ghc-8.6.5/inplace/bin/ghc-stage2" -o T8108 T8108.hs -dcore-lint -dcmm-lint -no-user-package-db -rtso
pts -fno-warn-missed-specialisations -fshow-warning-groups -fdiagnostics-color=never -fno-diagnostics-show-caret -dno-debug-output  -package unix
cd "../../libraries/unix/tests/T8108.run" && ./T8108  
Actual stderr output differs from expected:
diff -uw "/dev/null" "../../libraries/unix/tests/T8108.run/T8108.run.stderr.normalised"
*** unexpected failure for T8108(normal)

Second failure:

cd "../../libraries/unix/tests/libposix/posix010.run" && ./posix010  
Wrong exit code for posix010(normal)(expected 0 , actual 1 )
Stderr ( posix010 ):
posix010: getUserEntryForName: does not exist (no such user)
*** unexpected failure for posix010(normal)
