  PPC64: Poor StrictMath performance due to non-optimized compilation

Status in openjdk-8 package in Ubuntu:
  New

Bug description:
  ---Problem Description---
  Currently fdlibm optimization is disabled for PPC64, as a consequence StrictMath methods like, but not limited to, sin(), cos(), and tan() perform poorly. 
   
  ---uname output---
  Linux vm 4.4.0-47-generic #68-Ubuntu SMP Wed Oct 26 19:38:24 UTC 2016 ppc64le ppc64le ppc64le GNU/Linux
   
  Machine Type = pKVM 
    
  ---Steps to Reproduce---
  Please refer to:
  https://bugs.openjdk.java.net/browse/JDK-8170153
   
  Userspace package: openjdk-8-jre:ppc64el                 8u111-b14-2ubuntu2.16.04.2 

  Dear maintainer, please consider applying the fix already present
  upstream. Backport is trivial. Thank you.
