[PATCH] GCC compatibility: pass -z linker options to the linker

[Joerg Sonnenberger]

Sorry, wrong review. -R as alias for -rpath was the most common flag seen in the clang builds on NetBSD. Please keep in mind that GCC will effectively pass *all* unknown flags down to ld, which is why this sort of issue appeared in first place. That's also why I am quite strongly opposed against adding more non-driver flags in the front end.
