In this branch [1] I have a WIP for this.  First patch basically
consolidates access Linux implementation and it uses the strategy
to check for __NR_access first (and since it on sysdeps/.../linux
it should not worry about __SYS_*).

Second one is the __access_errno implementation.  It basically handles
the 3 cases (hurd, nacl, and Linux) by adding the __access_errno on
access.c.

I think it should a cleaner solution to __access_noerro (less macro
handling and build objects).
