How to modify CONFIG_CPU_TYPE in .config

I'm building OpenWrt from source to run in QEMU for a research project. I want to use an x86-64 build since it will be a little easier for my purposes. when I go through the process of downloading and building all is successful except it won't run in qemu as the default CPU type is "pentium4".

As I understand OpenWrt the build configuration is stored in .config. The .config file is created/modified one of three ways:

make menuconfig make kernel_config make defconfig

I've used the search option in menuconfig and kernel_config and I see no setting for CONFIG_CPU_TYPE. I manually changed the setting as well as the associated options and get a successful build with target_i386_i486_musl.

I'd rather not modify .config directly if I don't have to. What is the correct way to change this setting?

Manually changing/adding parameter in .config won't help, as those parameters are not defined in the framework. If you want to build it from the source then may be start by selecting

Target System (x86)
Subtarget (x86_64)
Target Profile (Generic)

in make menuconfig. OR You can directly download the x86 image and use it(external links).
