This reverts commit0841e2f820from 2011, which disabled plugin support in binutils for static toolchains, citing build system problems. This problem seems to be resolved. This also reverts part of45512b003dfrom 2017, which disabled LTO in gcc for static toolchains, citing problems on Arch Linux with loading the LTO plugin from a static binary.

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,

|

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
