Collision between binutils and clang [Mac OS]

[MarcoPolo]

Describe the bug
A simple project build fails on Mac OS

To Reproduce
On Mac:
git clone https://github.com/MarcoPolo/bug_repro1111
bazel build //main:hello-world

Fails.

Works on linux!

Expected behavior
Should build

Environment

• OS name + version: MacOS Catalina
• Version of the code: v0.7.0

Additional context
There should be way to set the priority of clang over binutils.

Indeed, the default Nix expression for nixpkgs_cc_configure

          with import <nixpkgs> { config = {}; overlays = []; }; buildEnv {
            name = "bazel-cc-toolchain";
            paths = [ stdenv.cc binutils ];
          }

causes a collision on MacOS. There are other issues with this as well. In particular nixpkgs' clang expects standard include paths in the environment, which are missing in the Bazel sandbox. You can use the setup from rules_haskell to work around this issue.

Note, #128 should resolve this issue as well.

I think this has been fixed by #128. Feel free to reopen if this is still an issue for you.
