mknative binutils 2.23.2 updates for m68000, mips64*, powerpc, sh3* and sparc

branches: 1.1.6; 1.1.12;
add all the binutils auto-generated files from matt-nb5-mips64 branch.
these are probably wrong and need to re-generated with mknative-binutils,
but get the build sort of limping along a bit better until then.

Rebase to HEAD as of a few days ago.

sync with head.
