The "Run Tests on qemu" section of run_wrapper.rst had a few issues left over from the last big documentation refactor[1]: - It referenced a non_uml.rst page, which was integrated into the other pages (including run_wrapper.rst). - It skimmed over the use of --arch= and --cross_compile= in favour of using a custom --qemu_config. Since most users will want to use the former, let's give examples. Remove the reference to the non-existant page, and add a couple of examples to encourage the use of --arch= and --cross_compile=. With this change, there should be no more broken references in the KUnit documentation (i.e., the one mentioned in [2] is gone).
