      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.

      Add an ld wrapper that calls to either gold or ld.

      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

        CTNG_LD_IS=bfd      will unconditionally call the old bfd ld linker
