This is the part in configure.ac that you are trying to trigger:

if test "x$with_mpfr$with_mpfr_include$with_mpfr_lib" = x && test -d
${srcdir}/mpfr; then
  gmplibs='-L$$r/$(HOST_SUBDIR)/mpfr/.libs
-L$$r/$(HOST_SUBDIR)/mpfr/_libs '"$gmplibs"
  gmpinc='-I$$r/$(HOST_SUBDIR)/mpfr -I$$s/mpfr '"$gmpinc"
  # Do not test the mpfr version.  Assume that it is sufficient, since
  # it is in the source tree, and the library has not been built yet
  # but it would be included on the link line in the version check below
  # hence making the test fail.
  have_gmp=yes
fi

And similarly with gmp.

Are you sure that you put the gmp and mpfr directories in the right
place?  ie, $(srcdir)/gmp?
