with {uint offset, uint syscall#} entries in libc & ld.so.
In libc a few syscall# entries (break, sigprocmask, _tfork, _threxit)
are duplicated because additional or inline uses occur (that situation
is handled elsewhere)

Add powerpc64 retguard macros for setjmp / longjmp.

ok deraadt@

Use a relative branch to jump from setjmp(3) into _setjmp(4).
Use correct register to reference the location where we store CR.

Use std instead of stw to store CR since we use std in sigsetjmp(3) and
we use ld to load it again in longjmp(3).
