Sure - getting the stuff out of petsc is easy; I can just read, say ${PCC}
and ${PCC-LINKER} with make. The hard part is to persist this in the
pkg-config file I create for petsc. As Garth mention, there is always the
option of using --variable=compiler. But I have to consider this "a hack"
and really want something cleaner if possible...
