Description

Introduce SPE ABI for PowerPC Book-E

Changes include:

New MACHINE_ARCH (powerpcspe)
Makefile changes to support the new MACHINE_ARCH
libc changes for fp* and setjmp
lim changes for fenv.h.
- Hard-coded the SPEFSCR SPR definition (512), to avoid #include-ing machine/spr.h
Toolchain changes to enable the ABI.

There is currently one gotcha -- when using -mspe, -mcpu=8540 is required, else
an internal compiler error is generated in gcc.

This ABI is incompatible with the standard 32-bit PowerPC ABI.
