Alas, this won't work -- that information isn't available here, and I
don't think substitutions work in the Architecture field anyway.

However, debian/rules can conditionally invoke dh with a suitable -N
flag.  I believe it should work to specify

  ifeq "" "$(wildcard $(libdir)/libfftw3l.so)"
  SKIP_NFFTL = -Nlibnfft3-long2
  endif
  
  %:
          dh $@ --parallel --with autoreconf \
                  --dbg-package=libnfft3-dbg $(SKIP_NFFTL)

and then conditionalize other commands involving the nfftl tree on

  ifneq "" "$(SKIP_NFTL)"

I am testing these changes now (against a checkout of your experimental
branch) and will follow up with a full patch if they work.

Good question!
