IMO, a package that can't build with fortify enabled is broken and ought
to be fixed.

That's acceptable as a temporary work-around, but ... a package not
being able to deal with fortify is very likely to be plain broken (and
harmful, likely to be suffering from memory leaks), which means you are
playing with symptoms and not providing a cure.
