I repost my reply for the list: Hello, I don't know any magic trick to do what you asked; What I usually do is to use distcc on the guest, and on the host run distccd-armv8. This way you can speed up compilation, though I can't tell you exactly by how much. You are not using native compilation though but cross-compilation this way. You can look at the distcc page on the wiki to know how to compile with distcc with or without makepkg. distccd-alarm-armv8 is available on the AUR.
