What's the "makeworld" target?  I've not heard of this.

This typically happens if "make obj" was not run before the rest of the
make targets.  Normally, the order is: make obj, then make depend, then
make (a.k.a. make all).

Is there a directory /usr/obj/usr/src/lib/libclang/Sema ?

Indeed, that caused the subdirectories under the obj directories to have
disappeared.  For some reason, in your situation, "make obj" is not run
correctly.
