Makefile: make it work for auto-completion

The latest autocompletion calls 'make -qp' to get all the possible
targets. This currently fails, as our makefile is calling itself
again and again ad-libitum.

Fix it by detecting that the recursion level is not 0, and bail out
if so. It works so well that it has the side effect of showing only
the 'public' target, and hide our internal ones! :-)

     7       Add support for the Signal Processing Engine.  This will set up
     8       the toolchain so that it supports the SPE ABI extensions. This
     9       mainly targets Freescale e500 processors.
    10       
    11       Setting this option will append "spe" to the end of your target
    12       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    13       configure/build system will know to include SPE ABI support. It
    14       will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
    15       and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
    16       do not need to explicitly add them.
