For amd64 it is probably not a very large problem; it's not used by default and those who have enabled it can likely adapt. However, it is used by arm64 and is the default linker in FreeBSD 11.1, so we'll need to go with either an errata fix or Kostik's p_osrel suggestion to avoid breaking the package builds.
