All I can think of is that glib's .gir files come with
gobject-introspection, whereas e.g., gtk3's .gir file comes with gtk3.
The reason is that gobject-introspection requires glib to build, so
glib couldn't depend on gobject-introspection to build it's .gir
files. (This is the way it is packaged upstream too.)

(Didn't look at the beginning of this thread, so don't know if .gir
were involved.)
