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! :-)

MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,

for e500v2 DPFP support) and will generate appropriate dual-precision

Note: If building a Linux kernel with this toolchain, you will want to make

     9
sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions

from getting into the kernel (which is currently unsupported). At this time,
yann@2173
    11
the kernel build system properly passes those two options, but older kernels

    12
were only passing -mno-spe by default."
