The `/compat/linux/usr/libexec/gcc/x86_64-redhat-linux/4.8.5/cc1` binary, installed by `cpp` RPM, needs `libmpc.so.3`, which is not installed or pulled by dependencies.
As it doesn't seem to be used anywhere else currently, I have added it to the list of RPMs installed by this port, rather than create a new port, in a manner similar to `libgomp`
