You might be able to get somewhere by writing a custom "main" function
in C and linking it in. According to
http://haskell.org/ghc/docs/latest/html/users_guide/options-phases.html
if a lib specified with the -l option during compilation contains a
"main", that will be used in preference to the one from HSrts.

You could presumably just extend argv with the "+RTS" "--RTS" entries
and then call into the one from HSrts, so this might even be quite
easy.
