From 347a00fb4ad2200f8f8331f8b366b1d84eff577d Mon Sep 17 00:00:00 2001 From: Roman Zippel Date: Sun, 10 Dec 2006 02:18:41 -0800 Subject: [PATCH] kbuild: don't put temp files in source The as-instr/ld-option need to create temporary files, but create them in the output directory, when compiling external modules. Reformat them a bit and use $(CC) instead of $(AS) as the former is used by kbuild to assemble files.
