Ouch.  An R_MIPS_GOT_PAGE against a global symbol?  OK, so it's supposed
to work, but gcc shouldn't really be generating that.  Can you send me
the .i file?

Not sure I understand.  We're supposed to order the master GOT so that
the symbols in the primary GOT come first.  Is that not happening for
some reason?
