Right!  That's the staged installation idea, except that you're
suggesting using a special MPFR installation directory, instead of a
generic $$PWD/install directory.

I have no objection to this idea; it is in fact what I would like to see
GCC do as well, so that we can run the testsuites without all of the
funny options and DejaGNU goo we use at present.
