Log message:
Add support for ELF64 user applications

- Add a new 64 bit system call table
- Set the PSW_W bit for ELF64 so they actually execute in wide mode

Still todo:

- Decide on the memory model for ELF64 (it currently uses the ELF32 limits)
- Actually get working 64 bit user land support...

Notes:

The changes to syscall.S stuff the PSW_W bit into the bottom of the
user stack, and use this as an indication of which syscall table to
use as well as whether to restore PSW_W.  This is necessary because
the syscall_exit return path to user space doesn't restore the flags
from regs->gr[0] in the task structure.
