FYI: I've not had any -r301975 problems with WiFi on my rpi2.

But I cross build for TARGET_ARCH=3Darmv6 with:

> XCFLAGS+=3D -march=3Darmv7-a -mcpu=3Dcortex-a7
> XCXXFLAGS+=3D -march=3Darmv7-a -mcpu=3Dcortex-a7

(And similarly for self-hosted.) It may be that the -march and/or -mcpu =
matter to the code generation and explain my lack of problems.

The builds also have INVARIANTS and WITNESS off.
