Sorry, I don't have a cross-compile system ready on my own.
I have some users that do ARM work and that's why I was concerned.

Anyway, I have finished reading the monster thread and at some point it
was proposed to have waf build a make file that wouldn't require python
in released tarballs but only for developers.

That looks like a very brilliant idea especially for talloc, tdb,
tevent.
I would very much like to have that to make talloc/tdb/tevent releases
simpler with less dependencies.



On another topic I disagree on renaming waf specific stuff to use
autoconf/automake and related build tools names, in
particular ./configure

It will totally confuse anyone that knows what ./configure normally is.
Given we are changing build system I see no issue in changing tools
names. Also a lot of packaging systems have smarts to add options that
they know ./configure support, so use ./configure may also cause strange
failures if we are not 100% compatible with what ./configure normally
allows.

Having a ./configure.waf or variations on the theme looks good enough,
and hints all people in the right way about what the tool does and how
it differs from "normal" configure files IMO.

Simo.
