As it turns out, ccache accelerates the build so much that it can trigger a race condition in the gobject-introspection subproject. This only surfaced recently as the introspection feature was previously disabled due to missing build time dependencies. The race condition surfaces as follows: the build breaks because gobject-introspection starts to build Gdk-4.0.gir before GdkPixbuf-2.0.gir, despite Gdk-4.0.gir depending on GdkPixbuf-2.0.gir.
