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

[Anton Blanchard]

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.
