Err.. but different ABIs at that level aren't really the same as
different OSABIs, though, right?

I.e. Linux/mips and NetBSD/mips both use o32 (same ABI) but different
OSABIs. Similarly, NetBSD/mips could support both the o32 and n32 ABIs
(well, once the n32 tools work :-), but they'd still use the same OSABI
because apart from the low-level, things like shared library handling,
signals, etc. are the same.
