Would be nice if you cheat by replacing /usr/bin/ld instead.
portmaster may miss some issues due to building in a dirty environment.

Fixed by https://svnweb.freebsd.org/changeset/ports/457591
Vulkan drivers always need py-mako since Mesa 17.3 but I didn't
try building only radv (either anv + radv or none).

freshports generates dependency list on amd64 but radv was also
built on powerpc*.
