[PATCH] ppc64: avoid 32bit only syscalls in unistd.h

Steve Munroe points out that ppc64 glibc builds stubs for a number of 32bit
only syscalls.  While none of them exist in the kernel syscall table, their
existence in unistd.h means glibc still tries to use them then falls back
onto the 64bit safe versions.
