This has worked, but some of the resulting binaries are not RELRO, which
is caused by %optflags not always being used during linking.  This is an
instance of the same problem seen with -fstack-protector, except that
here instead of a failed build we get no protection.

In general, do we want to use %optflags universally - that is, mix both
compiler and linker flags in it - or separate it into two somehow?
(Or into four, considering our separation for bin vs. lib.)
