All the discussion is about what happens when you assemble with
-mabi=n32 or -mabi=o64.  The reason n64 was mentioned was that there's
a linux hack that assembles n64 code with -n32.  The idea is that,
if all symbolic addresses are in compatibility segments, there's no
need to use %higher and %highest.  But the code still refers to
constant 64-bit addresses for I/O, etc.
