      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.

      By default, the wrapper will call to the default wrapper,

      but if you set the environment variable CTNG_LD_IS, you

      can change which linker will get called:

        CTNG_LD_IS=gold     will unconditionally call the gold linker
