Makefile.in has # Make sure the $(MAKE) variable is defined. @SET_MAKE@ configure has if eval test \$ac_cv_prog_make_${ac_make}_set = yes; then { $as_echo "$as_me:${as_lineno-$LINENO}: result: yes" >&5 $as_echo "yes" >&6; } SET_MAKE= else { $as_echo "$as_me:${as_lineno-$LINENO}: result: no" >&5 $as_echo "no" >&6; } SET_MAKE="MAKE=${MAKE-make}" fi from AC_PROG_MAKE_SET which seems to check whether make sets $MAKE. That appearantly succeeds for you. Do you "properly" do sth like MAKE=gmake ../configure so configure sees which make you are using? I think if your gmake doesn't set it then even recursive configure invocations from gmake will resort to 'make' but then I _think_ that gmake itself sets $MAKE (if it was not set?) for sub-processes. But maybe only if it thinks its recursive make?
