# XXX: This should ultimately use fixupOutputHooks but we currently don't have
# a way to enforce the order. If we have $runtimeDependencies set, the setup
# hook of patchelf is going to ruin everything and strip out those additional
# RPATHs.
#
# So what we do here is basically run in postFixup and emulate the same
# behaviour as fixupOutputHooks because the setup hook for patchelf is run in
# fixupOutput and the postFixup hook runs later.
