From: Ioan-Adrian Ratiu <adrian.ra...@ni.com> do_kernel_configme calls merge_config.sh (installed in the sysroot by the kern-tools-native recipe) which may invoke the compiler to complete the configuration process.
Depending on the build (and dependencies), this may error due to sysroot poisoning [1]. The errors are similar to: make[1]: Entering directory '4.1+gitAUTOINC+a7e53ecc27-r0/linux-x64-standard-build' HOSTCC scripts/basic/fixdep work-shared/x64/kernel-source/scripts/basic/fixdep.c:106:23: fatal error: sys/types.h: No such file or directory compilation terminated. make[2]: *** [work-shared/x64/kernel-source/scripts/basic/Makefile:22: scripts/basic/x86_64-nilrt-linux-fixdep] Error 1 Adding $TOOLCHAIN_OPTIONS to $CFLAGS before calling merge_configs.sh fixes the error because $TOOLCHAIN_OPTIONS defines the sysroot and make uses it to correctly compile & fill all missing kernel config options.
