Rebuilt with current binutils, now it did make emacs23-nox installable
on my loongson2f-based machine.  So this should be a loongson2f specific
problem.  I wonder whether a binNMU will be helpful, as I don't know
whether the patch works on non-loongson2f based machine.

Feel free to close this bug or handle it as appropriate.
