OK, that's useful to know, if a bit surprising. I'll explain why below.

I see that I conflated three issues: cross-compiling, X support and

My understanding was that, if you had the toolchain and a set of full
Qt X11 libraries for the target, then you could use pyqtdeploy to build
PyQt for the target. This is the cross-compilation issue which I assume
is solved. Would you use pyqtdeploy for cross-compiling to other
architectures running Qt on X11?

Non-X11 builds are probably simple enough to add support for.

I'm not tracking the evolution of the PyQt configure script these days,
but I don't think there's a nice way to handle feature-reduced builds
without either a lot of work to patch generated sip files or better
support in whatever generates those files.
