Yes and no. ;-) The Basis Library implementation is separate from the
compiler implementation. You'll want both a Primitive.MLton.sharedLibrary
binding in the Basis Library (using _build_const) as well as a
Control.sharedLibrary in the compiler implementation. The
Control.sharedLibrary will be affected by the command line flag and also
used in mlton/main/lookup-constant.fun to ensure that when the appropriate
_build_const is encountered in the Basis Library implementation it is
replaced by the boolean appropriate to this compile.

that needs to be treated differently when producing a shared library, so
it makes sense that Control.sharedLibrary won't be used elsewhere.
