Looks like we missed this =E2=80=98core-updates=E2=80=99 cycle.  :-/

To apply it without triggering a full rebuild, you could instead add a
phase that invokes =E2=80=98patch=E2=80=99 to apply it, only when the cross=
-compilation
target or system is GNU/Hurd.

Like:

  ,@(if (gnu/hurd?)
        `((add-before 'configure 'patch =E2=80=A6))
        '())  ;nothing

Could you try that?

Also please avoid reindenting the package at the same time as it makes
the patch a bit noisier.  :-)

Thanks,
Ludo=E2=80=99.
