kbuild: tell user how to make mrproper if ARCH has changed
Andrew reported that the following was broken:
make ARCH=alpha defconfig
setenv ARCH sparc
make mrproper
It would fail with:
Makefile:213: *** ARCH changed from "alpha" to "sparc". Use "make mrproper" to fix it up. Stop.
But running "make mrproper" resulted in exact same error message...
Teach kbuild to tell user how to run "make mrproper" to make it succeed.
The message generated by kbuild now looks like this:
ARCH changed from "alpha" to "sparc"
Makefile:210: *** Use "make mrproper ARCH=alpha" to fix it up ***. Stop.
So user now knows what to do to run "make mrproper"
