sh64: fix __NR_fgetxattr 2015-12-30T02:26:01+00:00 Dmitry V.

According to arch/sh/kernel/syscalls_64.S and common sense, __NR_fgetxattr has to be defined to 259, but it doesn't. Instead, it's defined to 269, which is of course used by another syscall, __NR_sched_setaffinity in this case. This bug was found by strace test suite. Signed-off-by: Dmitry V.

Ensure that the aux table is properly initialized, even when optional features are missing. Without this, the FDPIC loader did not work.
