miniz causes rchk to abort

[gaborcsardi]

If I keep miniz.o, I'll get this with rchk:

Running bcheck

------------------------------------------------------

Removing miniz.o fixes this. Maybe we could do this automatically, from configure. miniz and the other third party libraries are not needed for rchk, anyway.
