From: Stewart Smith <stewart@linux.vnet.ibm.com>

At least on the IBM Travis Enterprise instance, we can now do
ppc64le builds!

We can only build a subset of our matrix due to availability of
ppc64le distros. The Dockerfiles need some tweaking to only
attempt to install (x86_64 only) Mambo binaries, as well as the
build scripts.

Merged as of e101e85c9ff65e82f7ede4d5541d921b4a3ed923.

For those playing along at home, currently this only works on the
internal Travis instance. Hopefully at some point "soon" it'll be on the
public one. Wonderful magic elves inside IBM got it going internally
with working with the Travis team and they're piloting it internally to
iron out any issues.
