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.
