gold:

        * configure.ac (install_as_default): Define and set to false
        unless --enable-gold or --enable-gold=both/gold has been
        specified.
        * configure: Regenerate.

        * Makefile.am (install-exec-local): Install the executable as
        'ld.gold'.  If install_as_default is true then also install it as
        'ld'.
        * Makefile.in: Regenerated.
ld:
        * configure.in (install_as_default): Define and set to true
        unless --enable-gold=both/gold has been specified.
        * configure: Regenerate.

        * Makefile.am (transform): Use ld.bfd as the default name of
        the linker.
        (install-exec-local): Also install the executable as a binary
        named 'ld' if install_as_default is true.
        * Makefile.in: Regenerate.
