Unfortunately, we took a different route with GDB (with-...-prefix).
For instance:

--with-libiconv-prefix
--with-liblzma-prefix
--with-libbabeltrace-prefix

We already have a really nice macro that takes care of a lot of
configury for us with respect to lib depenencies, which I see
in gcc's root configure.ac that gmp/mpfr/mpc options is done
via specific code.

What I'm getting at is that, to achieve your prefered option
(which I agree is more elegant), it would take a significant
effort.
