My advice: do not run docker. I think this is a setting in the Travis file.
Otherwise the number of indirections becomes a tad too large:
Travis may itself run in VMs -> which runs containers --> in which
your run QEMU ....
A few too many moving parts IMHO.

So your goal is to limit the number of these and remove docker from
the equation.

As for the failure to build on various architectures, are you sure the
toolchain you use is compiled with support for these? It looks like it
from the Travis matrix though.
