I've taken the "Python 2 - missing 'test'" on a separate topic and
will merge it down to 'next' and 'master' to fast track.

The "override CFLAGS += CFLAGS_APPEND" thing looks good.

I am not sure how annoying people will find the V=1 output.  It is
irrelevant that it is in a collapsible section.  What matters is if
it helps those who *need* to expand that collapsible section to take
a look, or if it clutteres what they have to wade through.

When studying a build failure, I rarely found the exact command line
given by V=1 helpful, but YMMV---while I am not 100% convinced, let's
take the series as-is, because not losing information may sometimes
help even when we need to visually filter out extra clutter.

Thanks.
