Comment 16 for bug 1350435

Perhaps i don't understand what you are doing.

My understanding was that a package is being built (in the buildds) under qemu. Qemu is failing due to tcg failure. We want to tes twhether a qemu patch fixes it.

That's why I suggest installing the new qemu package on your host, using it to run a new server VM, and building the problematic package inside that VM. That way we can see whether the proposed qemu package fixes the build error.
