There's no -j recommendations so it will take a very long time to build Pony.

As part of the BUILD documentation, using -j should be documented for folks who aren't make power users.

This is especially important when building llvm for the make libs target. Note that -j must be forwarded to the CMake-generated makefiles, so rather than make libs -j6 one would require make libs build_flags="-j6" to do anything useful

Yeah I think we only need to advise it being used for make libs

Where j should be number of cores on the users machine or less.
