 I am trying to build ghc-7.8.4 as a cross compiler. After stage1 finishes
 and it tries to build libraries it detects that it can link against an
 existing -gmp and gmp.h (which is what I intended) and starts building the
 libraries/integer-gmp package against it. During the build it builds the
 inplace/lib/bin/mkGmpDerivedConstants binary for the target (genode) and
 then runs it on the build host (ubuntu linux), which leads to failure.

 The error emitted during the build is:

 "cp" -p libraries/integer-
 gmp/mkGmpDerivedConstants/dist/build/tmp/mkGmpDerivedConstants
 inplace/lib/bin/mkGmpDerivedConstants
 "rm" -f
 inplace/lib/mkGmpDerivedConstants
 echo '#!/bin/bash'                                                   >>

 my build environment is large and complex so I'm not providing all details
 here, but I will be happy to provide any supporting material needed, on
 request.
