Description Dan Horák 2016-07-13 15:30:32 UTC 
With the following spec file change I'm able to build openblas for ppc64

With only extending the ExclusiveArch I got into bug 1356152 which likely shows a bug in the openblas buildsystem (in ./test/Makefile). The %ifarch commands could be switched to %{power64} too.

Having both ppc64 and ppc64le subarches available would make it easier in packages that R: or BR: openblas.

Slightly better version, covers more from the ppc64 supported hw. Seems the DYNAMIC_ARCH supports only x86 :-( Would be useful for our ppc64 case ...
