Log message:
Retguard asm macros for powerpc libc, ld.so
Add retguard to some, but not all, asm functions in libc. Edit SYS.h
in libc to remove the PREFIX macros and add SYSENTRY (more like
aarch64 and powerpc64), so we can insert RETGUARD_SETUP after
SYSENTRY. Some .S files in this commit don't get retguard, but do
stop using the old prefix macros.
Tested by deraadt@, who put this diff in a macppc snap.
