From d9df92e22aca939857c5bc9ecb130ef22307ccc1 Mon Sep 17 00:00:00 2001 From: Sam Ravnborg Date: Fri, 7 Apr 2006 08:36:49 +0200 Subject: [PATCH] kbuild: properly pass options to hostcc when doing make O=.. This fix a longstanding bug where proper options was not passed to hostcc in case of a make O=.. build. This bug showed up in (not yet merged) klibc, and is not known to have any counterpart in-kernel. Fixed by moving the flags macro to Kbuild.include so it can be used by both Makefile.lib and Makefile.host.
