Having the name SHARED_SOURCE singular highlights that its a single file, which I think it should be.  But since its an internal variable, I would be OK with it having a different name.

I don't see a gain to making it multiple files, unless you are doing something very complicated, in which case, you'll need to customize the Makefile.  At that point, the Makefile is easy enough to read for someone who does Makefiles, so they don't need it documented.

It already is:

SHARED_SOURCE ?= $(wildcard lib$(LIBRARY_NAME).c)
SHARED_HEADER ?= $(shell test ! -e $(LIBRARY_NAME).h || echo $(LIBRARY_NAME).h)
SHARED_LIB = $(SHARED_SOURCE:.c=.$(SHARED_EXTENSION))
SHARED_TCL_LIB = $(wildcard lib$(LIBRARY_NAME).tcl)

I figured you'd want something more complicated, so I put in the ?= for you.  Like before with ALL_*, take the template and modify it for your library. If its implemented in a way that still meets the goal of a simple interface, I'll merge it in.
