OK, so let us get this straight.

What about cross-building? Could it happen that we build cross for x86 and while the native binaries are not with dispatch, we want the header available? But honestly, I am on very thin ice here with my experience! So feel free to completely rectify me if I am wrong. > Maybe Filter for DEB_HOST_ARCH_CPU instead, so it works on non-Linux arch, or Ah, indeed, that is a good point.

Yes, I haven't looked into the symbols by now, but yeah, that is probably a good idea. Thanks again, I will probably send another version tomorrow (evening here in Japan) for comments.
