 After pulling down the lates updates to my local GHC tree, I normally do
 the following:


 {{{
 hadrian/build.sh clean
 hadrian/build.sh --flavour=devel2 -j4
 hadrian/build.sh test --flavour=devel2 --freeze1 --only=T99999
 }}}


 The first test fails with: `Actual stdout output differs from expected:`

 stdout contains an additonal line, obviously generated by Hadrian:


 {{{
 +Linking /home/roland/Projekte/ghc/testsuite/mk/ghc-config ...
 }}}


 When I rerun the test, Hadrian does not re-link `ghc-config` and
 everything works fine!
