Any reason not to use the asm-generic version of this file?
If it didn't work, that is probably a bug in my code, not
yours, but they really look compatible.

I realize that this is the code I added to microblaze in my tree.
However, the four __ARCH_WANT_SYSCALL_* definitions are really
only meant as a transitional helper to get your code ported
from the older ABI. They should be removed from your file in
order to get the short system call list. Have you tried this?
In order to get there, you probably need to add a lot of wrappers
to libc along the lines of
int unlink(const char *pathname)
{
return unlinkat(AT_FDCWD, pathname, 0);
}
