You don't. 

A "shared library" is NOT a library, in structure, but more like an
monolithic object file (with special relocation information).

You need to build the object file you need to add like you build the
others you include into the (new) shared library, e.g.,

$(CC) $(OTHERCCFLAGS) -fpic -c gl.c # or for very big ones, -fPIC

to produce a gl.o which can be included in a shared lib.

Basically, if you dont have the sources, you can't; "static" libs
(libforms.a) normally contain objects not compiled with -fpic, because
they are slightly smaller and faster.

Your only option is to just add gl.o to the link command of the
programs you want to build, and to complain to the author of the forms
library (its semi-commercial, as I remember?)
