If kunit run happens in a tree in which a x86_64 kernel was built, the source tree could be dirty.
"make ARCH=um mrproper" will not clean the x86_64 build artifacts. Running "make ARCH=x86_64 mrproper" is necessary to clean them.
Add this information to the documentation.

- You may see the following error if a prior build leaves behind
- header files which 'make ARCH=um mrproper' fails to clean:
- "undefined symbol sev_es_trampoline_start referenced ..."
- This is special case scenario when a prior x86_64 build populates
- the source tree with arch/x86/realmode/rm/pasyms.h. This header
- will not be cleaned by 'make ARCH=um mrproper'
- If you encouter this problem, run 'make ARCH=x86_64 mrproper' to
encounter
Thank you. Will fix it.
