                    --with-mpc=/root/mpc/ --disable-multilib
           Product: gcc
           Version: 4.9.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: bootstrap

--with-mpc does not compile, installing mpc in standard location does.
RHEL 6 64 bit, latest patches. build as root.

sorry for the bug and run, but I purged all the files from the system already.
