How to connect to a Haskell static environment using cabal and stack without hard coding the ghc version?

I have a project that exports a shared static library and I use the next part in the file project.cabal

executable libsxp.so
    main-is:       Somefile.hs
    default-language: Haskell2010
    ghc-options: -shared -dynamic -fPIC -lHSrts-ghc7.10.2

The GHC version is controlled using Stack, so is there a way I can either get it, or add a version to do it -lHSrts-ghc{version}, or is there some kind of configuration for it? I tried to install

stack build --ghc-options='-O0 -lHSrts-ghc7.10.2'

but he does not seem to choose him.

Also, to clarify, cabal installStack is called, not by me.

Does this file bondage work? If so, then it should be enough to do something like this:

executable libsxp.so
    ghc-options: -shared -dynamic -fPIC
    if impl (ghc >= 7.10.2 && < 7.10.3)
        ghc-options: -lHSrts-ghc7.10.2
    else if impl (ghc >= 7.10.3 && < 7.10.4)
        ghc-options: -lHSrts-ghc7.10.3
    else if ...

, .so? .

, 7.10.2, 7.10.3? stack exec -- ghc --version
