Without any -j option, ninja will default to "-j (logical_cores + 2)".

The PARALLEL_MAKE value configured in OE isn't just about maximising
parallelism though (although that's it's common usage), it's also
useful to limit parallelism and reduce the load on the CPU. If
PARALLEL_MAKE isn't passed to ninja builds then they will always fully
load the CPU.
