Comment (by erikd):

 On my Aarch64 system, for `ghc-pkg` from the Debian version of ghc-7.6.4 I
 get:

 {{{
 $ objdump -DR /usr/lib/ghc/lib/ghc-pkg | grep stdout
 0000000001035d20 <stdout>:
                         1035d20: R_AARCH64_COPY stdout
 }}}

 where as for the newly compiled but broken 7.10 version I get:

 {{{
 $ objdump -DR /home/erikd/GHC/7.10/lib/ghc-7.10.1.20150414/bin/ghc-pkg |
 grep stdout
                         47bd60: R_AARCH64_GLOB_DAT
 base_GHCziIOziHandleziFD_stdout_closure
 000000000049a2e8 <base_GHCziIOziHandleziFD_stdout_closure>:
                         49a2e8: R_AARCH64_COPY
 base_GHCziIOziHandleziFD_stdout_closure
 }}}

 GHC 7.6.3 and 7.10 are different and so are Amd64 vs AArch64.

 It could well be a linker bug. The big difference between 7.6 and 7.10 is
 `DYNAMIC_GHC_PROGRAMS` is `YES` and as @juhp points out, this works when
 `DYNAMIC_GHC_PROGRAMS` is switched off.
