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 docker file allows creation of containers buildenv-cross-$ARCH for arm64, armel, armhf, mips, mipsel, mips64el, ppc64el, s390x, based off Debian 9, in which libvirt can be cross-compiled. Debian can support further architectures, but only by using the unstable 'sid' repos. This does not enable use of 'sid' but it could be added fairly easily at a later date if desired. Most of the other architectures are fairly old & obscure, the main interesting exception being riscv64. If qemu-user emulators are registered with the kernel binfmt, then it is theoretically possible to run "make check" tool, though this has not been tested. Signed-off-by: Daniel P.
