Hi all,
Colin, thanks for opening this Jira and also thanks to Steve Loughran and Edward Nevill for finding it.
We in OpenPOWER community and IBM, as part of our Hadoop 3.0 development plan, have unexpectedly come across this issue, build break due to the embedded x86 asm code :( 
Please, let me know if I can be of any assistance to you. Meanwhile we consider the latest Hadoop source code for Power architecture broken :( 
btw, could Hadoop community uncommitted these new x86 only enhancements?

> hadoop-mapreduce-client-nativetask fails to use x86 optimizations in some cases.  Also, on some alternate, non-x86, non-ARM architectures the generated code is incorrect.  Thanks to Steve Loughran and Edward Nevill for finding this.
