 I remember some talk about the "normal" PPC support and the PPC-SPE
(e500 type) not being possible to cater with one GCC... Therefore there
are two separate "PPC EABI targets" (or three via the '-eabialtivec')  :-(

SO:

- for the e300 you have to use a 'ppc-eabi' targeted toolchain

- for the e600 you have to use a 'ppc-eabispe' targeted toolchain

A Google search with "SPE", "e500", "Aldy Hernandez" (the SPE support
maker) could give more info...
