[Buildroot] [PATCH] fix the single character python file bug

[Yann E. MORIN <yann.morin.1998@free.fr>]

Charles, All,

Thanks for this quick followup.

The commit log should be formatted with a prefix that defines what is
touched and a brief description of the change. Then the body of the
commit log should contain a more detailed explanation. Eventually, we
will need that you sign-off your change.

For example:

    support/pycompile: support scripts with a single-charater filename

    We can only pre-compile files that can be imported; the regexp that
    filters filenames rejects filenames that contains a single
    character, although this is perfectly valid.

    Fix the regexp to accept those filenames.

    Signed-off-by: Your REAL-NAME <your-email@adress>

See: https://buildroot.org/downloads/manual/manual.html#submitting-patches

However, I have a question about your change, see below...

The current code in buildroot master looks like:

    if not re.match(r"^[_A-Za-z][_A-Za-z0-9]+\.py$",
                    os.path.basename(host_path)):

So your patch does not apply. What tree did you base your change on?

Otherwise, the change looks semantically perfectly correct.

Can you fix the above and resend a fixed patch, please?

Regards,
Yann E. MORIN.
