- Drop support for 32/32 fp register model

 - Fix siginfo structure definition
 - Ptrace fixes, one of them was an uninitialized pointer.
 - Header file fixes.
 - Fixes to linker scripts required for new binutils.

 - MIPS64.  Chainsaw edition.

Btw, Harald, why does the kernel no longer compile ...
