I also faced a similar problem during build. Someone suggested me to remove MPFR & GMP from the place you installed. Clear out every trace of GMP & MPFR from your system. Then make a folder named mpfr in GCC source code & put mpfr files into that folder. Similary make a folder named gmp in GCC source code & put GMP files into that folder. Then simply build WITHOUT --with-mpfr n all options. GCC would automatically install MPFR n GMP during the build. Give this a try once. It worked for me.
