This is all as expected. Now you have to turn to your Makefile, and see
whether these gl_LIBOBJS are correctly reflected in that Makefile, and
why the setenv.o is not being built.

This should not be a problem. Gnulib supports all autoconf versions >= 2.59
(see the DEPENDENCIES file).

Gnulib has already chosen to build the replacement function for setenv().
But something in or near your Makefiles is causing a problem.
