It looks like you are missing libmpfr which is used by gcc compilation process.
Buildroot should compile libmpfr for you before building gcc, I'm not sure
what is wrong.. Maybe some config setting is missing.
One solution would be to install the missing libmpfr on the host machine via
emerge/apt-get/or-whatever-you-use (after all it is used only on host machine,
right?).
