buildrom-devel/packages/kernel/kernel.inc
buildrom-devel/packages/uclibc/uclibc.mk
Log:
This patch adds -jN support to speed builds. It passes it as an
argument to make for the kernel and uClibc. It breaks the build for
busybox, so it isn't passed there.
The default is -j1, or the status quo.

+ This can speed the build if you have more than one core that you
+ would like to allow make to use. If you have a single processor, use
+ the default (-j1) otherwise, try processors+1 (-j5 for 4 processors).

+ This option currently only speeds up the kernel and uClibc builds.
