This one seems like it would break a lot of workflows, and contributor
muscle memory and scripts.  get_maintainer.pl and checkpatch.pl
are probably in quite a few people's scripts.

Also, I'm not sure '/build' is the right destination for this.  There
are a lot more things in there than just build scripts.  If you really
want to remove the top level 'scripts', it might be best to put
the  scripts from top-level '/scripts' into '/tools/scripts', which is
mostly empty now.
