[PATCH 3/3] RTEMS: Add e6500 multilibs for PowerPC

[Sebastian Huber]

Use 32-bit instructions only since currenlty there is no demand for a
larger address space.  Provide one multilib with FPU and AltiVec support
and one without.

This patch should be applied to GCC 4.9 and mainline.  I do not have
write access, so in case this gets approved, please commit it for me.
