The first issue to run into is the locales dependency. The package is Arch: all and not Multi-Arch: foreign. Rather than figuring out how to make it work, I observe that it is only used inside dh_auto_test, so annotating the dependency <!nocheck> is feasible. At that point, it becomes irrelevant to cross building. With that change in place, librsvg's dependencies become theoretically satisfiable. Unfortunately, apt sees a difference to practice. The rustc and cargo dependencies are interpreted has host architecture dependencies, so they would get us tools that cannot be run. Since they are multi-target tools, we need their native version. While the rustc dependency normally includes libstd-rust-dev, it gets us the wrong libstd-rust-dev once rustc is annotated :native, so libstd-rust-dev must be added to Build-Depends explicitly. At this point, Build-Depends can be installed. Unfortunately, meson refuses to configure. It objects to enabling the introspection and vala features as we cannot run host binaries. Indeed, there is no known way to run the g-ir-scanner without actually running host binaries, but on Debian the tool hides this fact and transparently uses qemu when needed, so meson doesn't actually get to run host binaries. For vala, the story is different. It actually doesn't require running host binaries. I'm not sure whether removing the "meson.can_run_host_binaries()" calls is acceptable upstream, but it certainly is not generally correct. With that change, meson manages to configure librsvg. Unfortunately, it does not pass a host triplet to cargo, so the Rust components are built for the build architecture. librsvg's meson.build expect that you pass the relevant triplet via -Dtriplet= and to be precise, a Rust triplet rather than a GNU triplet is expected here. /usr/share/rustc/architecture.mk can compute the relevant value. Then, the build proceeds quite far until meson launches the wrong vapigen. This is not a bug in librsvg but in meson itself and it is reported as #1126007. Please consider applying the attached patch.
