Where GMP, MPC and MPFR compiled for the same hardware as you are
building on? One possibility is that they were compiled for a newer
x86 processor, and so use instructions that are not supported by the
machine you're building on.

You would avoid that kind of problem by not installing those libs
separately. See https://gcc.gnu.org/wikiInstallingGCC for how to make
it much easier.
