The common way to link COBOL to COBOL is to use statically linking and
only produce one executable. This *should* be covered in the GnuCOBOL
manual.

Either something like
   cobc -static bar.cob foo.cob

or (likely more reasonable with bigger environments using make)
something like the following

all: foobar

SUFFIXES = .cob .$(COB_OBJECT_EXT)
FOOBAR_OBJECTS = foo.$(COB_OBJECT_EXT) bar.$(COB_OBJECT_EXT)

.cob.$(COB_OBJECT_EXT):
   cobc -static -c $<
foobar: $(FOOBAR_OBJECTS)
   cobc -static $(FOOBAR_OBJECTS) $<
