Comment (by yama):

 This bug seems to apear on Debian ppc64 port, too.
 If we believe the build logs of Debian's autobuild system for ppc64,
 building of ghc 7.6.1, 7.6.2, and 7.6.3 with ghc 7.4.1 succeeded.

 http://buildd.debian-ports.org/status/logs.php?pkg=ghc&arch=ppc64

 Howerver, building of ghc 7.6.3 with ghc 7.6.3 is looped.

 I don't know that there is relationship with this, buildings of Gtk2Hs
 package with ghc 7.6
 have also looped on ppc64.
