* Get grpc from nix on unix
The one from Bazel seems to cause linking issues when trying to run
things in GHCi. I’ve spent some time trying to use rules_foreign_cc to
build gRPC using CMake but decided that for my own sanity it’s better
to not pursue that further.
* Address review comments
* Add missing module load
* Cleanup GHCI_SCRIPT
* use the correct file ending on macos
* Import is_linux
* Switch back to grpc-1.23
The newer version seems to cause issues in combination with the java libraries.
* Try to fix package_app on macos
* more debugging
* Maybe this is not necessary, we will never know
* linkers are the worst
* Remove debugging output again
* readd rpaths
* treat libdispatch specially
* remove hack
* more fooling around
* lalala
rules_haskell looks for stack in PATH. On Windows it is provided by
dadew (i.e. scoop). rules_haskell then symlinks (copies on Windows) the
stack binary. Unfortunately, this breaks with scoop as the shim file is
then not found.
