That's not enough, see the description of --with-gmp in the installation docs.
It's simpler if gmp and the other libs are not linked to dynamically,
which means you should build them with --disable-shared, or even
simpler, just put the gmp sources under the gcc source tree (in a
directory called just 'gmp') and similarly for mpfr and mpc.

Searching for 'error' is a waste of time, the configure script works
by trying lots of things, then based on what works and what doesn't it
sets up the build makefiles for your system. That means the word
error will occur in places where things don't work, but that's not a
problem. Only the specific error message from the fatal error matters
("cannot run C compiled programs")

I'm not sure what this error means - do you have a working gcc
installed that can actually compile successfully for your system?
