Date: Fri, 13 Jul 2007 20:16:34 +0200 (CEST) From: Bodo Eggert <7eggert@....de> To: Linux Kernel Mailing List <linux-kernel@...r.kernel.org> cc: kai@...maschewski.name, Tony Breeds <tony@...eyournoodle.com> Subject: [PATCH] mkmakefile: include ARCH on O= builds If you build using O=builddir ARCH=bar, you'll currently need to supply ARCH= on builds from the builddir, too. With this patch, the generated Makefile will do that instead. make ARCH= will still override the Makefile default, allowing existing scripts to work correctly.
