[PATCH v2 2/4] debian: Pass --build and --host to configure

[Bastian Germann <bage@debian.org>]

xfsprogs fails to cross build because it fails to pass --host to configure.
Thus it selects the build architecture as host architecture and fails
configure, because the requested libraries are only installed for the host
architecture.
