The discussion in the ticket seems like it would only apply to
programs written in C/C++, but it doesn't say this.
Since other languages are usually much safer than C/C++ and the aim of
this is security, it seems like we should explicitly exclude other
languages from the requirement.
As long as there is a single exploitable module in the address space
(and there pretty much always is - libc or the language runtime),
having relro for all modules helps.
Anyway, redhat-rpm-config will probably set gcc flags, which excludes
other languages automatically - and I don't think this is really a
