92 gold is a new, optimised, multi-threaded linker with support
93 for plugins. Designed to be a drop-in replacement for the

95 bigger ratio being not uncommon, YMMV.

154 but if you set the environment variable CTNG_LD_IS, you
155 can change which linker will get called:
156 CTNG_LD_IS=gold will unconditionally call the gold linker
157 CTNG_LD_IS=bfd will unconditionally call the old bfd ld linker
