aarch64 7.8.4, 7.10, 7.11: lib/ghc/bin/ghc-pkg --version does not output from subprocess

(I first mentioned this recently in ticket:7942#comment:89016 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 (closed), and ran into:

"inplace/bin/ghc-cabal" copy libraries/haskell2010 dist-install "strip" '/builddir/build/BUILDROOT/ghc-7.8.3-38.fc22.aarch64' '/usr' '/usr/lib64/ghc-7.8.3' '/usr/share/doc/ghc/html/libraries' 'v dyn '

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 (ticket:7942##9673 (closed))
