Comment 2 for bug 1880564

you may have already done this analysis, Alberto, but fwiw what I see is that dpkg-architecture is used at runtime to get the multiarch path - however, this is always called in the context of the native architecture, so this can instead be calculated at build-time and embedded in the binary since this is in an arch-dependent package. That would solve the problem of needing dpkg-dev at runtime.
