Because the particular bit of QEMU code which was wrongly returning
the host ENOSYS rather than the guest ENOSYS happened to be
MIPS-specific.

Yes.

I imagine because not very many people use QEMU for MIPS in
linux-user mode. Often with QEMU things work OK at the point
they were last tested, but new guest features (like this new
syscall) can cause breakage.
