That would actually provide the pie benefit automatically for all
static executable, yes. Otherwise static pie will be a nice thing, but
not actually largely used in practice. And most people won't actually
realize it.

But then the piece which is saying that glibc's startup code is not in
use can be fixed into not using static-pie, can't it?
