We are building our software with a Yocto SDK we created against our imx8m board. We would like to be able to execute unit tests (C++ tests written in Google Test) quickly without having to copy our unittest binaries over to an actual imx board to execute them. For sanity, we are also building our linux distro for MACHINE=qemux86-64 and beaglebone-yocto.  So we have SDKs for imx8m, qemux86-64 and beaglebone-yocto. 

Is there a MACHINE type that we could build that would be suitable for executing compiled C++ google test binaries directly on Ubuntu 18.04 or 20.04? 

Thanks
