Well, at the end, I couldn't generate a working CWM, but it didn't
matter.  The wiki instructions I was following to flash CM on Huawei
SnapTo were misleading, in the sense they only indicated how to do it
with a CWM/TWRP recovery image, but the CM recovery image was well
suited for the task, :-)  So no need to build a CWM/TWRP image after

BTW, great work on Arch for all android components, the flows work
pretty much out of the box, :-)
