 (I first mentioned this recently in ticket:7942#comment:42 but I thought
 better to open a new ticket for this.)

 I tried to build ghc-7.8.3 on aarch64 Linux (Fedora 21 development) with
 the patch from #7942, and ran into:

 }}}

 The problem seems to be that the installed (dynlinked) ghc-pkg does give
 any output!!
 (eg "ghc-pkg --version" returns "", same for --help.)
 When I try the built binaries I find that
 ghc-7.8.3/utils/ghc-pkg/dist/build/tmp/ghc-pkg (which is statically
 linked)
 works normally (ie it outputs --help and --version) whereas
 $DESTDIR/$libdir/ghc-7.8.3/bin/ghc-pkg gives no output on stdout!

 A workaround is to build with DYNAMIC_GHC_PROGRAMS=NO
