Sorry Jean-Pierre,
but you are mistaken:

global LDFLAGS are passed to libtool, as seen in this extract
of the "src/Makefile" in the build tree.

libglpk_la_LINK = $(LIBTOOL) --tag=CC $(AM_LIBTOOLFLAGS) \
        $(LIBTOOLFLAGS) --mode=link $(CCLD) $(AM_CFLAGS) $(CFLAGS) \
        $(libglpk_la_LDFLAGS) $(LDFLAGS) -o $@
