It would be nice if you could fix your e-mail client to not rewrap the

The bootstrap compiler is provided as a binary only thing,
pre-compiled. So it works only on the architectures it was compiled
for. At least, that's why I remember from previous series on this topic.

It apparently needs to be extracted within the bootstrap compiler tree,
i.e in $(@D)/rustc, I guess that's why. But Eric can give more details
