Summary: Provide hooks into the autoconf configure script to define where libgmp and libmpfr may be found. Use these and opam to copy the more exotic library objects into the installation of infer on a new `make install-with-libs` target so that the binaries can be distributed usefully, i.e., without users having to install gmp, mpfr, and more importantly apron and elina (which need ocaml + opam + ..., which would defeat the point of having binaries).
