Subject: [bug#50201] [PATCH 01/52] gnu: dbus-glib: Support cross-compilation.

From: Maxime Devos <[email-masked]>
Date: Wed, 25 Aug 2021 20:02:41 +0200

This allows cross-compilation to succeed when not using
QEMU's transparent emulation, and the cross-compilation
is not a pointless cross-compilation like x86_64 -> i686.

* gnu/packages/glib.scm (dbus-glib)[arguments]: Set --with-dbus-binding-tool
  to a native version of "dbus-binding-tool" when cross-compiling.
