x11-drivers/nvidia-drivers: attempt fatal GCC_PLUGINS warning

Seen a user miss the warning and wondering why it didn't just
die for attention. Was formerly worried it may die when it
shouldn't, but the exact string check makes that unlikely.

Fairly rare that this is an issue nowadays though, GCC_PLUGINS
are typically not actually in-use and so errors don't happen
(check won't trigger then either).

Test isn't perfect, doesn't consider some configurations
(just informational, so not very important), but still fix
with -native-symlinks while here.
