Robert Scott e0f6367446 cc-wrapper, binutils-wrapper: add tests hardening-flags-handling
most tests use debian-devscripts' hardening-check, so only work on
ELF systems and can only detect a limited subset of flags.

some extra tests actually execute fortify-protected programs and
should be slightly more universally applicable.
