From: Michal Marek Date: Tue, 7 Jun 2016 09:57:02 +0000 (+0200) Subject: kbuild: Initialize exported variables X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b36fad65d61fffe4b662d4bfb1ed673c455a36a2;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git kbuild: Initialize exported variables The NOSTDINC_FLAGS variable is exported, so it needs to be cleared to avoid duplicating its content when running make from within make (e.g. in the packaging targets). This became an issue after commit 9c8fa9bc08f6 ("kbuild: fix if_change and friends to consider argument order"), which no longer ignores the duplicate options. As Paulo Zanoni points out, the LDFLAGS_vmlinux variable has the same problem.
