Simple script to build all configs

[Olof Johansson <olof@lixom.net>]

Jeremy asked for it, so I figured more might have use for it. Simple
script to build all defconfigs for an arch.

I use it with ARCH and CROSS_COMPILE set outside of the script, i.e. 
$ ARCH=powerpc ~/bin/buildall


I also pass in TARGET="vmlinux modules" in cases where default targets
don't build (very common on ARCH=ppc).



#!/bin/sh

export CC="ccache gcc"

make mrproper

for config in arch/$ARCH/configs/* ; do
	CONFIG=`basename $config`
	echo -n $ARCH.$CONFIG: ;
	yes "" | make $CONFIG >buildall.log 2>&1
	if make $TARGET -j 5 >>buildall.log 2>&1 ; then
		mv buildall.log $ARCH.$CONFIG.log.passed
		echo "	passed"
	else
		mv buildall.log $ARCH.$CONFIG.log.failed
		echo "	failed"
	fi
done
