[poky] [RFC PATCH 1/1] local.conf.sample: update suggestions for BB_NUMBER_THREADS and PARALLEL_MAKE

[Joshua Lock]

It's been suggested that BB_NUMBER_THREADS should be 2 * the number of cores
and PARALLEL_MAKE should be equal to the number of cores available on the
build machine.

Update local.conf.sample to suggest this.
