Would it be possible to use an amended gprbuild configuration file? Here
on Mac OS X there's an option

   for Shared_Library_Minimum_Switches use
         ("-dynamiclib", "-Wl,-flat_namespace", "-shared-libgcc");

and you could add your required option in there.

No good for gnatmake, of course.

I put in "-Wl,-foo" and rebuilt a shared library, and as expected the
result was

$ gprbuild -Pbc --config=botched.cgpr
gprlib bc.lexch
/opt/gnat-gpl-2011/bin/g++ \
  -dynamiclib -Wl,-flat_namespace -shared-libgcc -Wl,-foo \
[...]

(don't know where g++ came from!)
