[Xen-devel] [PATCH] qemu-xen-traditional: allow build without blktap1

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

I intend this to become optional at the xen build level so it needs to become
optional here. Until the matching Xen patch is applied and exports
CONFIG_BLKTAP1=y|n there should be no change.
