The part of debian/rules.defs is:

ifndef DEB_STAGE
# Ada --------------------
ada_no_cpus     := m32r sh3 sh3eb sh4 sh4eb
ada_no_systems  := 
ada_no_cross    := yes
ada_no_snap     := no
ifeq ($(single_package),yes)
  ada_no_cpus += m68k powerpcspe sh4 sparc64
  ada_no_cpus += alpha
  ifneq (,$(filter $(DEB_TARGET_ARCH),m68k mips mipsel powerpcspe sh4
sparc64 hurd-i386 kfreebsd-i386 kfreebsd-amd64))
    ada_no_cpus += mips mipsel
    ada_no_cpus += hurd-i386 kfreebsd-i386 kfreebsd-amd64
    ada_no_snap := yes
  endif
endif

and later

ifneq (,$(filter $(DEB_TARGET_ARCH_CPU),$(ada_no_cpus)))
  with_ada := disabled for cpu $(DEB_TARGET_ARCH_CPU)
endif

The problem is not ada_no_snap but ada_no_cpus causing gnat1 no longer
found by the gcc-4.9 compiler driver.
