Change condition from "stub_ver >= 6" to "stub_ver == 6". In upcoming v7 don't look into emb_ov at all.
This is a pure legacy, pre-v6 I think.
It is set on stub ver >= 7 and tells dynamic linker that static crt0 is not here (payloads are split). It allows to delay the resolution of upl, which is later done by second loader.
Instead check the needed flag in plt.S.
With stub-v7 and second loader we are no longer interested in that. Second loader is libelf-based and can do many things, so we need to off-load to it as much as possible, keeping the stub simple.
In v6 there was an extra field to jump to emb_ov, but it is not in v7. So we get directly to 64bit ELF and need to load dyn.
