I don't believe this one is actually a bug. Or rather it's an annoyance
that was already present on the 32bit Goldfish and I don't see a way of
avoiding it.

Goldfish is an Android emulator not a PC, if you build a Goldfish kernel
it won't run on a PC and mixing the setup gives nonsense results.

I don't know of any way to reliably detect we are running on Goldfish.
Given that it's easy enough to fix up a bit so I'll see if I can find
any documented way to detect Goldfish.
