Not disable plugin support altogether, but disable assuming the linker
supports the plugin. If user uses explicit -f{,no-}use-linker-plugin,
it is his problem to care that the linker has support. But the problem
is that when build-time ld is new enough gcc assumes it has to support
the plugin. And that is not the case.
