[libvirt] [jenkins-ci PATCH v5 5/5] lcitool: support generating cross compiler dockerfiles

Debian's filesystem layout has a nice advantage over Fedora which is that it can install non-native RPMs in the main root filesystem. It is thus possible to prepare an x86_64 filesystem containing -dev packages for a foreign architecture, along with a GCC cross compiler. QEMU has used this technique to facilitate developer build testing of non-x86 architectures, since few people have access to physical hardware for most of these architectures. For the same reason it would be helpful to libvirt developers. This patch extends the 'dockerfile' command to 'lcitool' so that it accepts a '-x $ARCH' argument. $ lcitool dockerfile -x s390x libvirt-debian-9 libvirt This is only valid when using a 'deb' based distro.
