Given that x86_64 is way more complex then ARM it is not *that*
surprising.
I think the fact that they're using userspace emulation rather than system
emulation is actually the biggest difference to the setup I was using, and
accounts for a significant part of the difference in slowdown. (Note that
userspace emulation wasn't an option at all in my setup, for x86_64 on 32-
bit x86.) To know for sure, we'd have to measure how long it takes to do
builds with qemu-system-arm, assuming we can get that to work at all.
