@item --enable-gold
Enable support for using @command{gold} as the linker. If gold support is
enabled together with @option{--enable-lto}, an additional directory
@file{lto-plugin} will be built. The code in this directory is a
plugin for gold that allows the link-time optimizer to extract object
files with LTO information out of library archives. See
@option{-flto} and @option{-fwhopr} for details.
@item --with-plugin-ld=@var{pathname}
Enable an alternate linker to be used at link-time optimization (LTO)
link time when @option{-fuse-linker-plugin} is enabled.
This linker should have plugin support such as gold starting with
version 2.20 or GNU ld starting with version 2.21.
