Ah, I've just looked into dpkg and it seems to switch to `gtar`
invocation if such an executable is present.  So it failed only because
I haven't rebuilt dpkg after we've switched to installing GNU tar
as `gtar`.  In this case, there is nothing to be fixed in dpkg and we
just need to handle this on Gentoo end.

I'm sorry for the false report and thank you for all your guidance.
