PATCH: add ctr and lr to clobbed registers.

[Johan Rydberg]

The current PowerPC syscalls sometimes generate invalid code.  This
patch fixes it (I hope so anyway.  It has fixed all of my problems for 
now).

Also included is the correct relocation code for PowerPC.

2003-10-16  Johan Rydberg  <address@hidden>

        * powerpc/l4/bits/stubs-init.h (__L4_SETUP_SYSCALL): Do correct
        relocation (that means none).

        * powerpc/l4/bits/syscall.h (__L4_PPC_XCLOB): Add ctr and lr.
