Bug#803477: petsc: FTBFS against mpich

thanks

Testing the petsc build on s390x yields this error

 #  error 'Please use the same version of GCC and g++ for compiling MPICH and user MPI programs'

The error comes from /usr/include/mpich/mpicxx.h:

#ifdef __GNUC__ 
# if __GNUC__ >= 5 
#  if __GNUC_MINOR__ > 2 && 2 == 2 
#  error 'Please use the same version of GCC and g++ for compiling MPICH and user MPI programs'
#  endif
# endif     
#endif


So mpich on s390x was built with gcc 5.2.  But current gcc used by /usr/bin/mpicc.mpich is 5.3.


Looks like mpich needs to be rebuilt on s390x.  I've flagged this in bug#807318
