What sort marking would be best?  A fake section, like .gnu.mips.sym32?
(suggestions for a better name welcome)  That's easy to do in gcc and
wouldn't need any new as/ld flags.

Or should it be an ELF header flag?  A proper note section?

An alternative (...idle thinking, probably a bad idea...) might be to
add a new relocation type which is calculated like R_MIPS_HI16 but which
complains about non-32bit addresses.  Then add a %reloc() operator for it.
This'd definitely be more work though...
