Before start descending, Kbuild needs to run 'prepare' and 'scripts',
which has been orthogonal to each other.
Going forward, let's consider 'scripts' is a part of the preparation.
This will allow more cleanups.
Move 'scripts' to the prerequisite of 'archprepare', where UML starts
compiling target *.c files.
