Hi Gustavo,

we've realized that we have exactly the same problem on Linux/s390 so
I hope you don't mind that I've updated the bug and the webrev to also
include the fix for Linux/s390:


The top-level change stays the same (I've only added the current
reviewers) and for the jdk change I've just added Linux/s390 as
another platform which can compile fdlibm with HIGH optimization.
