It *is* linking them, but it isn't pulling any objects from them
(or at least not the objects you expect to be pulled),
because nothing in them is in the librarian's *needed* list.

You should *not* be using -static if you want your executable to
run on any systems other then the one it was built on (building
anything with -static is a very bad idea(TM)), but that's completely
orthogonal to your current problem.

The answer above (and understanding and the linker.html I mentioned

GNU-ld specific solution (assuming you really do want all of 
libbf libot and libfm to be included in the executable):
