Kbuild. Remove linux name references.
This commit substitutes references to the linux string in variable names. It changes the LINUX prefix and uses the TIMO prefix (short for tiny mountain) It changes the vmlinux prefix for tinymountain prefix. It preserves linux references found in licenses, comments giving credits and from scripts that are not supported by the current build system yet, like rpm generation.
