powerpc-linux-gcc vs ppx_8xx-gcc and ppc_6xx-gcc

[Lixin Yao]

Hello, All,

I use ELDK 4.2 to work on platforms, one with MPC860 and the other with
MPC8248.

In installation, I see links:
ppc_8xx-gcc -> ppc-linux-gcc
ppc_6xx-gcc -> ppc-linux-gcc
ppc-linux-gcc -> powerpc-linux-gcc

I understand ppc_8xx-gcc needs to be used for MPC860 and ppc_6xx-gcc
needs to be used for MPC8248. But both point to the same
"powerpc-linux-gcc". 

What are the differences between powerpc-linux-gcc, ppx_8xx-gcc and
ppc_6xx-gcc? What's the default target processorr of powerpc-linux-gcc?

Thanks.
