Subject: [PATCH] Random123 - provide a patch to fix compiles with IBM XL
(#11028)
* Newer versions of IBM XL no longer define `__xlC__`, but define `__ibmxl__`
instead. This one-line patch fixes this problem in Random123.
* This patch was also provided to the Random123 maintiners
(Random123@DEShawResearch.com). I don't expect a new release from them for a
while, so I believe that this patch is the correct path forward (for now).
