add patch to fix strange problem with incorrect output spec, that's being triggered when WRF is built with iqacml toolkit

reset CC to MPICC, requires during configure (otherwise hdf5.h include test fails becasue mpi.h is not found)
add -DgFortran to CPPFLAGS when building with GCC

get rid of example easyconfigs for WRF/WPS with goalf toolkit (GCC 4.6.2), turns out to be too much hassle to get build working (code needs to be patched in various places)

add patch file to fix mpi.h include order (only needed when --enable-unsupported is used with Intel-based toolkit?!?)
