Since #442965, the `go run` command that `libcap` does at one point is no longer able to use the linker included in the go compiler, so it uses `$CC` instead. But `libcap`'s `Makefile` uses the wrong compiler for this. This patch has been submitted to the maintainer upstream. Include it in nixpkgs for now, until it's accepted and a new release is made.
