OpenRISC is in the kernel under arch/openrisc and the syscall numbers we
user are just like other architectures, it's in:

  linux/arch/openrisc/include/uapi/asm/unistd.h

This then includes the generic numbers:

  linux/include/uapi/asm-generic/unistd.h

There are other architectures in the kernel, like arm64, risvc, nios2 using the
generic syscall numbers.

Should QEMU also have linux-user/generic/syscall_nr.h that mirrors the generic
file in linux?  This way this could be maintained in just one place.

I actually have a patch to add syscall numbers for openrisc which I am using to
test our new glibc port right now.  I will clean if up and submit for review.

It looks like for 5.0 we would need to get changes in by March 23:

I'll try to aim to get my change up for review soon then.
