Comment (by juhpetersen):

 (another +1 for NCG for arm and arm64! :-)

 Likely I should open a new ticket, but I am having trouble with
 installing ghc-7.8.3 plus above patch on Fedora 21 ARM64 (aarch64).

 }}}

 The problem seems to be that the installed (dynlinked) ghc-pkg does no
 output anything!
 (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!

 Maybe I should try installing statically linked ghc and see if that makes
 difference.
