We must be talking about separate things:

$ head -n3 Makefile
build:
        echo CPPFLAGS: $(CPPFLAGS)
        echo DEB_HOST_MULTIARCH: $(DEB_HOST_MULTIARCH)
$ cat debian/compat 
9
$ fakeroot debian/rules build
dh build 
   dh_testdir
   dh_auto_configure
   dh_auto_build
make[1]: Entering directory `/tmp/dhtest-1.0'
echo CPPFLAGS: -D_FORTIFY_SOURCE=2
CPPFLAGS: -D_FORTIFY_SOURCE=2
echo DEB_HOST_MULTIARCH: 
DEB_HOST_MULTIARCH:

Which means I can't use DEB_HOST_MULTIARCH in the config-scripts,
unfortunately.
