pread/pwrite: handle renamed syscalls in common/ppc/xtensa code
Some arches got this fix, but many did not. So copy the ifdef logic to the ones that missed it to fix behavior in linux-2.6+. URL: https://bugs.busybox.net/show_bug.cgi?id=5258 Reported-by: David Laight <david.laight@aculab.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
