Thanks but I see all four of:
g++-4.4_4.4.6-11 g++-4.6_4.6.2-4 gcc-4.4_4.4.6-11 gcc-4.6_4.6.2-4

in that line.  Mmm.  I also see:

: # configure
cd /build/buildd-gnat-4.6_4.6.2-2-armel-bK1oIn/gnat-4.6-4.6.2/build \
	  && PATH=/build/buildd-gnat-4.6_4.6.2-2-armel-bK1oIn/gnat-4.6-4.6.2/bin:/usr/lib/arm-linux-gnueabi/gcc/bin:$PATH \
		CC="gcc-4.4" \

further down.  This is a result of this in debia/rules2:

ifeq ($(REVERSE_CROSS),yes)
  CC	=
else
  CC	= $(if $(filter yes,$(with_ada)),gnatgcc,gcc)
  ifneq ($(PKGSOURCE),gcc-snapshot)
    # doesn't bootstrap using gcc-4.5 on armel
    ifneq (,$(filter $(DEB_TARGET_ARCH), armel))
      CC = gcc-4.4
    endif
  endif
  ifeq (,$(findstring gnat,$(PKGSOURCE)))
    ifneq (,$(filter $(DEB_TARGET_ARCH), kfreebsd-amd64 kfreebsd-i386))
      CC = gcc-4.4
    endif
  endif
endif

I see that Matthias has just removed this bit in svn; this means that
merging from gcc-4.6 4.6.2-5 will actually fix this bug.
