From: Felix Fietkau Date: Thu, 16 Mar 2017 08:53:30 +0000 (+0100) Subject: build: add KERNEL_MAKE and KERNEL_MAKE_FLAGS variables and move to kernel.mk X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0aed054becb2143952bfb77cb64e23c83ce79dfd;p=openwrt%2Fstaging%2Fflorian.git build: add KERNEL_MAKE and KERNEL_MAKE_FLAGS variables and move to kernel.mk This allows packages to use kernel make options without the forced -C $(LINUX_DIR). It also makes it more clear that it to be called from kernel module packages directly.
