Bug#853285 closed by Clint Adams <clint at debian.org> (Bug#853285: fixed in ghc 8.0.2-3)

[John Paul Adrian Glaubitz]

Attaching an updated patch which has been tested to not break native builds.

The patch modifies debian/rules such that for cross-builds, the recommended
build options for GHC are used (i.e. -O0 and building with the embedded libffi).

In order to cross-build GHC for a given architecture, one can now simply use
sbuild with the --host= and --profile= parameters:

sbuild -d sid --host=m68k --profile=cross ghc*dsc

Only caveat is that haskell-devscripts-minimal has to be manually pre-installed
in the build chroot because of the known issue with arch:all packages [1].

Upstream has also added lots of changes to improve cross-builds even more [2],
so we can expect to be smoother with GHC 8.2.0. The biggest thing that is still
lacking for cross-compiled versions of GHC is the missing documentation and
Haddock.
