kde packages and hurd

[Samuel Thibault <samuel.thibault@ens-lyon.org>]

Hello,

KDE packages used to build fine on the Hurd port.

Since recently, we have started seeing this build error:

“
  Your current platform 'GNU' is not supported.  The list of supported
  platorms is 'Linux;FreeBSD;Windows;macOS;Android'.If you think this is a
  mistake or you are working on enabling the platform please build with the
  KF_IGNORE_PLATFORM_CHECK variable set to true
”

We have tried to make kde add the Hurd in the list of supported
platforms, but they'd only do it if there is active support with CI
setup etc., see:

https://invent.kde.org/frameworks/extra-cmake-modules/-/merge_requests/294

I wonder what debian KDE maintainers' position is: would it be fine
to just make debian/rules with KF_IGNORE_PLATFORM_CHECK set for some
platforms? Or add the platform in extra-cmake-modules and add the
supported platform as a patch in the packages?
