[petsc-dev] configure error

[Smith, Barry F.]

  Well you may be trying to build with gcc-7 but you are building C++ with clang

gmake[2]: Leaving directory '/Users/markadams/Codes/petsc/arch-macosx-gnu-g-omp/externalpackages/mpich-3.3a3'
gmake[1]: Leaving directory '/Users/markadams/Codes/petsc/arch-macosx-gnu-g-omp/externalpackages/mpich-3.3a3'clang: error: unsupported option '-fopenmp'

 --with-cc++=gcc-7 is not correct.
