[OE-core] [PATCH] local.conf.sample: Have comments ready to go for quad-core (4 -> 8).

[Trevor Woerner]

All of these "solutions" assume the user wants to use all of their
entire computing resources to do nothing other than their Yocto build.
This isn't _always_ the case, is it? :-)

Personally, I know this build is going to take time. So I start it,
then go off and do other things with my computer. In my case, I don't
like it when the other things I'm trying to do on the computer are
bogged down due to this all-consuming, background build task. I would
much rather that whatever else I'm doing remain responsive to me.
Whether the build finishes in 20 minutes or 25 is irrelevant because
I'll only notice it's done 30 minutes from now :-) As such I never set
my settings to "full power"... knowingly and purposefully.

This being said, I think what is currently in the sample config file
(which are roughly half of full power) are good defaults. If you're
new to this kind of stuff, these settings will suit just fine. If
you're a power user, you'll know how to set them to 8 or 16 or any
other setting which suits your needs.
