[petsc-dev] make -j not supported? Why???

[Jed Brown]

This is to support different backends. If configure found CMake, then
normal "make" will use multiple jobs, or you can do it explicitly with make
-j3 $PETSC_ARCH.

CMake would be terrible as a hard dependency (it's terrible enough as it
is) but it's less bad than some alternatives.
