Generalise this test so that it works on more than qemux86-64: - Don't edit a file in arch/x86 to cause a rebuild, instead use init/ - Look for the edits in the build tree, as the deployed kernel could be of any type (zImage/bzImage/etc) and edits may be in the compressed part. Also remove redundant checks on the result of runCmd(), as this will raise AssertionError exceptions itself so the explicit asserts will never trigger.
