Linker flags vs. libraries

I am trying to build a couple of projects for the Fedora Linux distribution. These projects use dune to build. Fedora mandates that certain flags be passed to the linker (e.g., -Wl,-z,relro and -Wl,--as-needed). I cannot seem to find the correct way to do this. If I pass these flags along with the libraries to be linked with in c_library_flags, then the cmxs files are appropriately linked, but the stub libraries generated with ocamlmklib are not. In fact, ocamlmklib emits "Unknown option" warnings. What I need is some way to specify linker flags, which have to be guarded with -ldopt when passed to ocamlmklib, separately from the libraries to be used for linking. Does dune provide some way of doing this?

This seems to be related to #119.

Start by reading how dune handles c_library_flags and how ocamlmklib receives options, then review the related discussion in issue #119. The change is complete when linker flags such as -Wl,-z,relro can be specified separately from libraries and are passed correctly to both cmxs linking and generated stub libraries without Unknown option warnings.
