The kernel captures the compiler string in several places, some of which we are already fixing, but others we are not (as they don't cause issues). But when building an on target module, the main kernel Makefile compares compiler strings and outputs a warning similar to: warning: the compiler differs from the one used to build the kernel The kernel was built by: x86_64-poky-linux-gcc (GCC) 11.3.0 You are using: gcc (GCC) 11.3.0 We drop the cross compilation prefix from the captured compiler string, and we avoid the warning.
