      gold is a new, optimised, multi-threaded linker with support
      for plugins. Designed to be a drop-in replacement for the
      original linker, ld, it can be much faster, with a 5:1 or
      bigger ratio being not uncommon, YMMV.

      Both the historical ld and the new gold linkers will be
      installed, with ld being the default linker used.

      binutils can be extended through the use of plugins.
      Especially, gold can use the lto-plugin, as installed
      by gcc, to handle LTO.
