Subject: [PATCH] [KBUILD] Put the CROSS_COMPILE and ARCH variables in the build directory makefile
Date: Sun, 30 Sep 2012 17:20:05 -0600	[thread overview]
Message-ID: <20120930232005.GB30637@obsidianresearch.com> (raw)

To make cross building a little simpler. The usage with mini-config would
be something like:

$ mkdir build
$ make ARCH=arm CROSS_COMPILE=arm-v5te-linux-gnueabi- \
       KCONFIG_ALLCONFIG=mini.config O=build allnoconfig
$ make -C build/

After configuring subsequent builds do not need to specify the cross
options.
