V9 ABI gives more registers to application use.

Except that glibc uses those---in theory, as I see it, it should be compiled
with fixed g2 and g3 to leave them to the application.  I get it now.

It may be possible to make the workaround a big less ugly (I'm thinking of
avoiding #undef/#define by using assembly).  I made a patch (see attachment,
just FYI), maybe sometime I'll try it using self-virtualized qemu.

Yes, that's much better.

If it works. :-)
