collect2.c (main): Search PLUGIN_LD for plugin linker.

2009-11-08  H.J. Lu  <hongjiu.lu@intel.com>

	* collect2.c (main): Search PLUGIN_LD for plugin linker.

	* configure.ac (--with-plugin-ld): New.  Default to ld.
	* configure: Regenerated.
	* config.in: Likewise.

	* exec-tool.in (ORIGINAL_PLUGIN_LD_FOR_TARGET): New.
	(collect-ld): Use ORIGINAL_PLUGIN_LD_FOR_TARGET for -plugin.
