What are the goals of a mass rebuild now, given that we just had one
before F21 Beta?

A *lot* of packages broke in the F21 mass rebuild.  I spent the better
part of two months helping fix FTBFS bugs until Alpha freeze.

The F21 included new versions of gcc and openjdk, and a new default
compile flag (-Werror=format-security), all of which caused major
breakage.  Without knowing what the goals are for this rebuild, it's
hard to say for sure, but I doubt this time would be quite *that* bad.
