mpc-1.0.3 build errors

Looks like messed up library versions and headers. You may have gmp and
mpfr and mpc alreayd installed in system locations or other places.

Isolate your build process into one place and be sure to setup the usual
LD type environment variables to only "look" into those places for the
headers and libs. Perhaps your CFLAGS will need to force the RPATH and
the RUNPATH in the output elf headers with -Wl,-rpath=/some/path/lib or
similar.
