Well, I have no idea what some sort of detection kicks in if you remove the
mapping as Debian doesn't currently have an "arm" architecture which could
be mapped to arm-unknown-linux-gnu for rustc.

I would just include the mapping to make sure this is not your problem. It's
not that it takes much work to do that, no?

Well, I never had any problems in this regard when explicitly specifying the
architecture in the configure call. Why would you rely on guessing in such
a case?
