I see lots (probably all) of ghc-* packages, so filing one against
ghc-rpm-macros or ghc itself would probably be the most expedient there.
If it is just a missed flag or something, it can be rolled up with the
7.10.0 rebuild which I believe is planned for Rawhide.

Of course, if ghc doesn't support everything checksec looks for,
ignoring everything under %{_libdir}/ghc-*/ would be best. Jens?

For any CMake-using projects (I see at least CMake itself and ParaView
in the list), setting the `POSITION_INDEPENDENT_CODE` property[1] on
targets would fix any missing -fPIE. It is initialized with
`CMAKE_POSITION_INDEPENDENT_CODE`, so adding:

    -DCMAKE_POSITION_INDEPENDENT_CODE:BOOL=ON

to %cmake when hardening is enabled should fix -fPIE missing. Anything
with internal static libraries *might* need a scalpel to turn off the
property on those targets.
