This is due to the new glib-version-detection code that was checked in.
I had a configuration using clang, which does not appear to support the
mechanisms that are being used to tell what version of glib is being
linked against.

Practical upshot is that I can't even clean my clang configuration
because our makefile insists on re-configuring before it tries to clean.

Fam, didn't you have patches to allow e.g. cleans and "make tags" and so
on without re-incurring a full reconfiguration?
