[PATCH v2] generic syscalls: Wire up statx syscall

From: Stafford Horne
Date: Mon Mar 13 2017 - 10:46:09 EST

The new syscall statx is implemented as generic code, so enable it
for architectures like openrisc which use the generic syscall table.

Fixes: a528d35e8bfcc ("statx: Add a system call to make enhanced file info available")
