Ok. Can I take this as an acked-by for the check-bin-arch / pkg-generic changes then? ;)

Can I take this as an acked-by for the check-bin-arch / pkg-generic > changes then? ;) I haven't reviewed the implementation details, but on the general principles, yes, I'm OK. It's a bit annoying to extend the package infrastructure for such a specific case, but I don't really see a better solution here, except hacking libmpeg2 to remove the runtime detection logic. On the other hand, do we care enough about libmpeg2 on SPARC to extend the package infrastructure just for this purpose? In the end, even if Waldemar's solution is not "correct", it avoids the need to extend the package infrastructure just for a purpose of a single package that will most likely never ever be used on SPARC. Arnout, what do you think? Best regards, Thomas

When I spun that patch, I expected there would be more use cases than just libmpeg2. But the autobuilders don't point to anything obvious, so perhaps not. I've marked as Rejected in patchwork. We can pick it up again if something else turns up. Regards, Arnout

Don't forget to submit it upstream as well. Upstream looks very inactive to me, I don't think I will submit it there. best Waldemar

The output detection recognized wrong target output, because sparcv9 optimization flags used for sparcv8 build.
