Make MPC85XXSPE kernel conf ident match the file name

Start building modules for MPC85XX and MPC85XXSPE

These kernels aren't restricted to development boards anymore, they are
closer in behavior to GENERIC, so build modules.

Merge ^/head r323559 through r325504.

Stop passing -me500 to the assembler for Book-E kernels

We already pass -many to the assembler, and -me500 drops 64-bit instruction
handling, for some reason only breaking module building for 64-bit

Additionally, build with CTF for dtrace.

Add some more devices to the MPC85XX-based configs

These devices bring the configs closer to a desktop-like (GENERIC) kernel
config.
* The Freescale DIU support was added to the config in r306358.

Without keyboard support video support is nearly pointless, so add ukbd and
ums.
* The AmigaOne X5000, and P1022 devboard, both use a variant of the ds1307 RTC
* cpufreq scaling is currently supported by the p1022. More SoCs will be added
eventually.

Create a new MACHINE_ARCH for Freescale PowerPC e500v2

Summary:
The Freescale e500v2 PowerPC core does not use a standard FPU.
Instead, it uses a Signal Processing Engine (SPE)--a DSP-style vector processor
unit, which doubles as a FPU. The PowerPC SPE ABI is incompatible with the
stock powerpc ABI, so a new MACHINE_ARCH was created to deal with this.
Additionaly, the SPE opcodes overlap with Altivec, so these are mutually
exclusive. Taking advantage of this fact, a new file, powerpc/booke/spe.c, was
created with the same function set as in powerpc/powerpc/altivec.c, so it
becomes effectively a drop-in replacement. setjmp/longjmp were modified to save
the upper 32-bits of the now-64-bit GPRs (upper 32-bits are only accessible by
the SPE).

Note: This does _not_ support the SPE in the e500v1, as the e500v1 SPE does not
support double-precision floating point.

Also, without a new MACHINE_ARCH it would be impossible to provide binary
packages which utilize the SPE.

Additionally, no work has been done to support ports, work is needed for this.
This also means no newer gcc can yet be used. However, gcc's powerpc support
has been refactored which would make adding a powerpcspe-freebsd target very
easy.

Test Plan:
This was lightly tested on a RouterBoard RB800 and an AmigaOne A1222
(P1022-based) board, compiled against the new ABI. Base system utilities
(/bin/sh, /bin/ls, etc) still function appropriately, the system is able to boot
multiuser.
