Description of problem:

Upstream commit 29bb8f07da9110fa167b55e5013de80adfd1e99b redefined those two functions. It break OPA-FF compiling. One of those duplicated functions should be removed.

    umad: Replace htonll macros with proper inlines and mark deprecated
    
    This allowed code using these public definitions to continue to compile
    but will get warnings from gcc. Users should move to glibc's endian.h
    
    We want to avoid new users of these macros in our tree.
