Hello,
the issue is positive vs. exclusion list:

Architecture: some long list without ia64

needs to be kept up-to date constantly, including even unofficial
architectures. While

ifeq ($(DEB_BUILD_ARCH),ia64)
        some-magic
endif

continues  work no matter whether there are 2 or 25 non-ia64 archs.

I does not. -Nguile-gnutls does not seem to end up in dh_listfiles
environment, even if I have
export DH_OPTIONS=-Nguile-gnutls
as the *very* *first* noncomment line; and therefore I get:
--------------------
dh_installdirs -pguile-gnutls 
dh_installdirs: I have no package to build
make: *** [install/guile-gnutls] Error 1
dpkg-buildpackage: failure: fakeroot debian/rules binary gave error exit status 2
--------------------

Looks like make does not pass on exported variables to $(shell) constructs:
--------------------------------
ametzler at argenau:/tmp/GNUTLS$ cat Makefile
DH_OPTIONS := -Nguile-gnutls
export DH_OPTIONS
TESTVAR := $(shell printenv | grep DH)

blah:
        @printf 1;echo $(TESTVAR)
        @printf 2; printenv | grep DH
ametzler at argenau:/tmp/GNUTLS$ make
1
2DH_OPTIONS=-Nguile-gnutls
--------------------------------
