Well, not really, in the sense that having libgdk.so depend on
libglib.so (etc.) is, while something we create on platforms where it
works, not something we depend on; the whole idea of glib-config
was that we would provide the complete set of libraries when
linking the app so inter-library dependencies aren't required.

(After all, they still aren't available on every platform.)

IIRC libtool-1.3.x just ignores dependencies of libraries on .la files.
