local.conf.sample: Add automatic defaults for BB_NUMBER_THREADS and PARALLEL_MAKE
Its rather sad that people don't appear to read local.conf and then complain about slow builds when they're just using a single thread. Most systems have more than one core now so we might as well use a more automatic default for these values. This may lead to better experiences for new users. [YOCTO #2528] (From meta-yocto rev: 52bf4bdcaea0df69231327413d502aad11c3adf3) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
