OpenBLAS-0.2.11 was released August 2014 so maybe your CPU is newer and
therefore unsupported (although it happens to build OK here). There have
been several releases since then (latest is 0.2.19 Sept., 2016) which
may support your CPU. Perhaps the maintainer (Cc'd) could update the
SlackBuild.

In the meantime, using DOWNLOAD url of:

https://github.com/xianyi/OpenBLAS/archive/v0.2.19/OpenBLAS-0.2.19.tar.gz
gives a saner tarball name than the style produced by the url in the
current .info file.
