 Compiling a simple "hello-world" program with an amd64/linux to
 aarch64/linux cross compiler built from the current `ghc-7.10` branch
 results in a binary that segfaults as soon as it is run.

 A cross compiler build from the master branch works and I thought it also
 worked for `ghc-7.10`.

 A native aarch64/linux compiler built from the `ghc-7.10` branch works
 correctly.
