OK - so a simple 'make -q vmlinux' check, except that the way we utilise
make will let it fail at first build command.
That will obscufate things even more in kbuild - but I will give it a
try sometime. It will be easy to cover 95% but to reach 100%
predictability will be though.
- file dependencies is easy
- command line changes is relatively easy
- but the various scripts and user commands will be tricky..

Not on the top of the TODO list though.
