[Qemu-devel] [PATCH] configure: ignore spice libraries on 32 bit.

[Rusty Russell <rusty@rustcorp.com.au>]

As featured on:
        https://bugs.launchpad.net/qemu-linaro/+bug/928432

Since we compile with -Werror, the presence of spice headers breaks
compile.  Yet except for x86-64, it doesn't compile, doesn't work, isn't
supported.  See: http://spice-space.org/faq.html
