Hi!
We ICE with -Wp,-pie, as -pie (and -shared/--pie/--shared) are marked as
Common options, but aren't handled in the cc1/cc1plus/etc. options handling.
Fixed by making those options Driver specific, and for the time being add
their help strings to display_help.
Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?
Alternatively there is a second (untested) patch.
