a27e685fa0 Align .TOC. for PowerPC64
This change, with prerequisite 0e5fabeb, provides a toc base aligned
to 256 bytes rather than 8 bytes.  This is necessary for a minor gcc
optimisation, allowing use of d-form instructions to correctly access
toc-relative items larger than 8 bytes.

71a39c98f8 Change plt stubs to have destination in r12.
This change is to support the new ELFv2 ABI, which uses the value in
r12 on function entry to calculate the got/toc pointer.

	reg and r12 as destination.
