Doesn't the build system know the version of GCC being used to compile
glibc?  If so, could it conditionally enable/disable the plugins?

I would suggest to make this a configure option at first, resulting in abuild failure if the plugins are not buildable. Auto-detection of acompatible GCC version can be tricky. What we don't want is that theauto-detection determines the plugin to be incompatible, and thensilently disables it.
