'meson-build-system' includes 'patchelf' as an implicit input for all packages that use it, and uses it from its 'fix-runpath' phase, sometimes directly and sometimes via (guix build rpath).
'patchelf' is a nasty hack which seems to only work on Intel-based systems. It certainly doesn't work on 'mips64el-linux', and when I last investigated it seemed hard to fix this. As far as I can tell, it has never built successfully on 'armhf-linux' either: https://hydra.gnu.org/job/gnu/master/patchelf-0.8.armhf-linux/all I don't know about 'aarch64-linux'. Given that 'meson-build-system' is seeing increased usage in some important packages, e.g. 'libinput' and several GNOME packages, this is becoming an increasingly serious problem for non-Intel platforms.
