I only posted patches for an  arbitrary subset of targets because

1. Not everyone is interested in --enable-default-pie.
2. I can't tests all targets myself.

If patches for all targets is the only blocker before the patch
will be approved or target maintainers will help me test the patch,
I will post patches for each target affected.
