[OE-core] PowerPC / gcc / prelink

I finally chased down the PowerPC prelink problem. It appears to be within GCC.
On most systems GCC (for PPC) is configured with --enable-secureplt. However,
the OE-Core version is not. The prelinker assumes that for certain types of
relocations that the PPC_GOT table will exist, otherwise it gives up. (It
doesn't know how to do the relocations in the old style .bss-got table.)
I'm wondering if there is a reason that PPC is defaulting to the old style
.bss-got (other then the secureplt was not enabled by default).
Is this something we should do in all cases, or should this become a
DISTRO_FEATURE like the mips 'mplt' setting?
I'm still building systems and running tests, but adding --enable-secureplt to
both the gcc-cross-initial, and gcc-cross appear to have resolved the prelinking
issues.
