[PATCH 0/8] Rationalise the pkg-config variables

Hi,

This series cleans up and rationalises the pkg-config variables, with the
goal of following the majority of major distros and later switching from
pkg-config (last release: 2017) to pkgconf (last release: June 2025).

However, this series doesn't do that.

The first three patches are adding missing inherits, or fixing a bug in
numpy that we were lucky enough not to hit.

The next two are the key patches, specifically "classes/pkgconfig: rationalise
variable usage" is the meat of the series that actually changes the
variables and contains the rationale.

The next two are improvements for pkgconf that we might as well apply now.

Finally, a controversial patch to drop support for a working menuconfig on
kernels older than 5.15. If there is a need to support 5.10 then the small
fix to the kernel Makefiles should be an easy backport. This patch is not
needed though, and can be dropped.

Cheers,
Ross
