I know this is not very helpful, but: The BeagleBone Black is surely
not a platform I'd want to compile on... It'd be great if "we" [1]
could come up with a well-documented way to do cross-compilation for
these types of targets. IIRC this was one of the results that Philip
Balister concluded from GRCON'14's embedded working group meeting;
maybe he wants to comment on that.

Greetings,
Marcus

[1] quotation marks due to the fact that out of lack of embedded
platform I'm not part of "we".
