The last time I spoke to you about this, I got the impression that the
only problem you'd found was the one we solved by switching relocs
against local symbols to be against symbol 0.  Now are you saying that
you found this problem with global symbols too?

And that the versions of binutils and glibc on linux-mips.org are
binary incompatible with the rest of the world?  Ugh!
