dev-util/gdmd: add 14

Additionally:
- use symlinks instead of hardlinks for gdmd -> ${CHOST}-gdmd
- call gcc-config in pkg_postinst if the selected configuration matches
  this package's SLOT. This creates a symlink under /usr/bin which is
  required for rdmd from dev-util/dlang-tools to find the default compiler.
- restrict tests as there aren't any.
