How is it not working? Can you post the error? I can imagine that
debhelper gets confused if you invoke dh_auto_build multiple times, but
I can't say for sure.

Oh, and you should use make to handle the loop, instead of using the
shell inside make. Then make can parallelize if you 'make -j', and
things will just work better. Below I'm also not invoking dh_auto_build
multiple times, so it might fix your issue too. Something like this:

  ALL_BUILD_TARGETS := $(foreach D,Axi 3D, $(foreach N,1 2,hifimagnet$D_P$N_N$N))
  override_dh_auto_build: $(ALL_BUILD_TARGETS)

If your debian/rules has rules for building hifimagnet$D_P$N_N$N then
you're done. Otherwise you need to tell it how to do that. If you're
punting to some other Makefile, tell it that:

  $(ALL_BUILD_TARGETS): hifimagnet%:
          $(MAKE) $@
  .PHONY: $(ALL_BUILD_TARGETS)
