The problem reported by the testsuite is real, and ignoring it means
that bzip2 compression support is broken on s390x (and other 64-bit
big-endian architectures).
The problem is that some pointers are casted from long to unsigned int,
while they do not have the same size. The patch below fixes that using
a temporary variable as the pointer. There might be better solutions
like changing the variable type, but I leave that for the upstream.
