- Added ability to provide (optional) path to the kernel sources

- Fixed path for ${s}/conf/files.FOO and a note that it should be merged into
corresponding file to be able to compile the kernel
- Changed kernel configuration example with the driver: it is not produced by
copying Generic but by including it
- Changed from automatic module building to asking an user if it whants to
