Sometimes you can't build mpfr mpc and gmp within the gcc source tree  
for some targets. We found that out in CLFS. That's we we don't build  
gmp mpc and mpfr within the tree. Works okay for x86 and x86_64,  
however, when you start building for other targets, it becomes hairy.  
You may want to try to build gmp mpfr and mpc separately.
