Thanks.

But now I am seeing that some of these files have not been deleted in my
tree:

    lisp/emacs-lisp/comp.elcivrXZS
    lisp/window.elc9aaVMg

This might be because I interrupted the build process at some point; I
don't know.

These files don't get removed when I run extraclean or bootstrap.  So if
we just ignore them there is a risk that these files will slowly build
up over time.

Perhaps we should also make sure they get cleaned up when building, as
in the attached.

Another alternative, arguably more correct, would be to figure out
exactly under which circumstances these files gets left over and delete
them there.  (There is a let-bound `kill-emacs-hook' in
`byte-compile-file', which might be a good place to start looking.)
What makes this a bit tricky is that this is somewhat hard to reproduce.
