So the autobuilds were failing for these two weeks since
commit e43386c1 was *totally*
braindead: there's no "arm-e17" target neither "arm-kde4" one.

Fixed while awake and adjusted (in sync with build node)
to reference particular nexus7 and not just "arm".

The sad thing is that it should now read "nexus7old" TBH,
2013 model is not Linux friendly at all at the moment...
