Fails also, but at a later point:

What you need to do is the following:

Build the package on the system which you have at hand (amd64, i386, ...), directing the build output into a file. Search through the output to see whther there are any compiler warnings and fix them all. With that done the package should build on ppc64el.

Or look into the buildlog for amd64 on Launchpad to find all the warnings.
