If we break compatibility, we can do it the right way and also remove
support for glibc 2.0 from MIPS glibc (change shlib-versions).

What I'd like to see before I apply the patch:
- A patch for manual and FAQ mentioning that we break compatibility
  and that new binutils are needed.
- If possible a test for configure that we use the right binutils.
- A test of HJ's suggested patch.

Ralf, what do you think?
