[LinuxBIOS] r74 - in buildrom-devel: . packages/kernel packages/uclibc

[svn at openbios.org]

Author: jcrouse

New Revision: 74

Modified:
   buildrom-devel/Config.in
   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.
