Comment (by thomie):

 Actually, I don't see what is wrong with 525856. These are the 2 relevant
 changes.

 In `mk/test.mk`:
 {{{
 -       -e 'config.compiler="$(TEST_HC)"' \
 +       -e 'config.compiler="\"$(TEST_HC)\""' \
 }}}

 In `config/ghc`:
 {{{
 -    h = os.popen('"' + config.compiler + '" --info', 'r')
 +    h = os.popen(config.compiler + ' --info', 'r')
 }}}

 That should give the same result, shouldn't it?


 In mk/test.mk there are 3 pairs of quotes:
 * outer ' : this is a shell string
 * outer " : this is a python string
 * inner " : this is a path
