* sysdeps/unix/sysv/linux/mips/kernel-features.h [_MIPS_SIM ==
_ABIO32] (__ASSUME_STAT64_SYSCALL): Define.
* sysdeps/unix/sysv/linux/mips/mips64/fxstat64.c: New file. Based
on version from ../sysdeps/unix/sysv/linux/.
* sysdeps/unix/sysv/linux/mips/mips64/lxstat64.c: Likewise.
* sysdeps/unix/sysv/linux/mips/mips64/xstat64.c: Likewise.
