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.

|

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.
