For MPICH, according to the mpicc man pages, mpicc -compile_info shows the flags for compiling a program, and mpicc -link_info shows the flags for linking a program.

-showme (Open MPI) or -show (Open MPI, MPICH and derivates) use -showme:compile and -showme:link to obtain the options automatically
