Cannot find atlas on CentOS7

[Peter]

yat's configure won't find atlas on CentOS7 because it is installed as

$ ls -l /usr/lib64/atlas/
total 21304
lrwxrwxrwx. 1 root root       17 Aug 10 13:51 libsatlas.so -> libsatlas.so.3.10

From ​https://www.centos.org/forums/viewtopic.php?f=47&t=48723 I read that atlas no have merged libcblas libatlas etc into one single library. Well, actually two a serial and a threaded named libsatlas and libtatlas, respectively.

I tested linking against either of them and in both cases make check worked with no error.

(In [3453]) closes #839

Simplify code by looping over different cblas implementations using AC_SEARCH_LIBS rather than repeating code. Include search for satlas and tatlas, which are the names in new versions of ATLAS.
