[OpenWrt-Devel] [PATCH 1/2] kernel-build: ignore runtime config options during reconfig

[Petr Štetiar]

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
