UCX trunk fails to compile with stock gcc-4.8.4 on Ubuntu 14.04 on ppc64le

[cparrott73]

Describe the bug

I get a compilation failure with the stock gcc-4.8.4 included with the Ubuntu 14.04 distribution on ppc64le. My own gcc-5.5.0 build on the same system works fine. Not sure if this is a UCX issue, or an issue with gcc-4.8.4. It is not a problem for us to use gcc-5.5.0 instead, but I am just noting the issue here as FYI.

Here is the error:
