* Fix loadArchive clang++ error on macOS
GHC 8.6.4 introduced an issue where linking to `-libc++` will cause
GHC to resolve the library path to `c++` which in turn is a link to
clang++. This results in the following error:
```
ghc: loadArchive: Neither an archive, nor a fat archive: `/nix/store/?-clang-wrapper-5.0.2/bin/clang++'
<no location info>: error:
loadArchive "/nix/store/?-clang-wrapper-5.0.2/bin/clang++": failed
```
The provided patch reverts the linking behavior of GHC to not resolve
`-libc++` to `c++`.
