Support for e500v[12] patch proposal

At AdaCore, we find very practical to be able to define triplets like e500v2-*-*
to configure in particular gcc accordingly (select the proper cpu, config files
and fpu support).

This means that it should be treated as a powerpc target with an "spe" ABI
(expected for example for the "elf" of "linux" targets, checked in gcc config as
"elf*spe*" of "linux*spe*).

So I'm proposing the following patch. Any comment is very welcome.

Thanks in advance for your feedback,

Best regards,
- Jerome

    * config.sub: Decodes e500v[12]-* basic machine as a powerpc alias, and
    add a "spe" suffix to the OS for e500v1|2 ABI selection
    * testsuite/ Add tests for e500v[12]-elf,
    e500v2-wrs-vxworks, e500v2-vxworksae and e500v2-wrs-linux.
