Makefile.in has

# Make sure the $(MAKE) variable is defined.
@SET_MAKE@

configure has

if eval test \$ac_cv_prog_make_${ac_make}_set =3D yes; then
  { $as_echo "$as_me:${as_lineno-$LINENO}: result: yes" >&5
$as_echo "yes" >&6; }
  SET_MAKE=3D
else
  { $as_echo "$as_me:${as_lineno-$LINENO}: result: no" >&5
$as_echo "no" >&6; }
  SET_MAKE=3D"MAKE=3D${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=3Dgmake ../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?=
