Thanks for tracking the bug to the commit.
I think a trivial fix for this will be to merge the two "if"-statements:
"""
if (defined $override_type) {
if ($has_explicit_target) {
"""
To
"""
if ($has_explicit_target or defined(override_type)) {
"""
That should enable "free" overrides when it is necessary to completely
discard a command.
Additionally, there is another patch lying around that might make it
easier to run the inner loop (by replacing package_arch with an
"package_is_arch_all"). That should make -indep/-arch reasonable cheap
as well
Thanks,
