       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

       binutils can be extended through the use of plugins.

       Especially, gold can use the lto-plugin, as installed

       by gcc, to handle LTO.
