Subject: kernel-build: ignore runtime config options during reconfig
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=74acc160a959b50776b9012dc9122734c8a110da;p=openwrt%2Fstaging%2Fblocktrron.git

kernel-build: ignore runtime config options during reconfig

Don't put CC_HAS_ASM_GOTO, IS_GCC, IS_CLANG and GCC_VERSION runtime
config options into the kernel configs during reconfiguration as it
makes no sense, since these options should be set at runtime.

Fixes: FS#2588
