Originally, I have tried to remove TARGET_NR_open and others, they can
not pass building, and I also noticed about NR_openat. But at last, I
still remain TARGET_NR_open and others (with related comments):

 - Another platforms (e.g. microblaze, arm64) defined them, too.

 - It is only for linux-user, can bypass Linux tile kernel. So it is
   still correct.

 - It really wastes memory and storage a little, but for me, the related
   maintainers (not me) need to consider about whether let the code more
   complex or save memory a little.

OK, thanks. After read through, it is useful to me. :-)
