MarsSeed [1] filed a deletion request for lib32-hwloc [2]: Cleanup after the deletion of lib32-onetbb (PRQ#47125).
The latter used to be a dependency of lib32-suitesparse, but then its upstream dropped using tbb, so lib32-onetbb and this library were left without any downstream dependents. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/lib32-hwloc/
