Subject: [PATCH] makefiles/color: fix build on NixOS

On NixOS, there is no `/bin/echo`, instead
`which echo` will return

    /home/benpicco/.nix-profile/bin/echo

so hard-coding the path will break here.

Use `/usr/bin/env` to get the path of `echo`.
This should be availiable on all systems at the same location.
