[Qemu-devel] [PATCH] configure: add --disable-zlib-test

[Alon Levy <alevy@redhat.com>]

This is required for building libcacard which doesn't itself require
zlib without bringing in this requirement to the build environment.

Signed-off-by: Alon Levy <alevy@redhat.com>

I'd like this to go into 0.15.0 too, it makes building libcacard possible
without zlib-devel being installed.
