I think it is important to document what a hardened build means, in the
change request as well as provide a pointer from the packaging
guidelines. It's no much point mentioning hardened builds but no-one can
find out what are these flags and the rationale of being added to this
set. Currently it was implied they were flags to enable position
independent code, but as it seems there are other flags in this set too.
