You're right, it should have linked with the static libbz2 and zlib.  I
made a change in this area recently and didn't notice anything different
because I was using a cross compiler that doesn't have shared versions
of those libs in its sysroot.  I just committed a fix that should take
care of it.

Setup used to have a bundled libbz2, but that was before there was a
MinGW libbz2 in the distro, so now we just use that.
