+Subject: [PATCH] gdbus-codegen: drop distutils dependency
+
+Python 3.12 removed distutils from the standard library. GLib 2.46 still
+imports distutils.version in gdbus-codegen, which breaks host-libglib2 on
+modern Linux distributions before the rest of the toolchain can build.
+
+Replace the LooseVersion-based sort key with a small local parser so the
+code generator keeps the same version ordering without relying on any
+non-standard Python module.
