pyc files in source dir with O=

[Geert Uytterhoeven]

When running "make htmldocs O=/path/to/somewhere", *.pyc files end up
in the source tree instead of in the build tree:

    $ git ls-files -o
    Documentation/sphinx/kernel-doc.pyc
    Documentation/sphinx/kernel_include.pyc
    Documentation/sphinx/rstFlatTable.pyc
    $

This is with v4.8-rc5.

With next-20160907, two more files appear:

    Documentation/sphinx/cdomain.pyc
    Documentation/sphinx/load_config.pyc

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
