+From: Tor Hedin Brønner <torhedinbronner@gmail.com>
+
+Adapted from https://gitlab.gnome.org/GNOME/mutter/commit/c53c47ae123b03cc66044d2b846342123ecb3a01
+
+We only want to drop inheritable though, to prevent the ambient set leaking further than gnome-shell.

+Subject: [PATCH 6/7] build: bump ABI to sysprof-capture-4
+
+From: Christian Hergert <chergert@redhat.com>
+
+GLib will now be linking against sysprof-capture-4.a. To support that,
+sysprof had to remove the GLib dependency from sysprof-capture-4 which
+had the side-effect of breaking ABi.
+
+This bumps the dependency and includes a fallback to compile just the
+libsysprof-capture-4.a using a subproject wrap.
+
