Anyway, the compilers work. I tested some cross compiles and no issues showed up.

[root@wsfd-netdev30 ~]# repoquery --disablerepo=* --enablerepo=epel-testing -qa | grep cross cross-binutils-common-0:2.25.1-31.el7.1.noarch cross-gcc-common-0:4.8.5-16.el7.1.noarch [root@wsfd-netdev30 ~]# grep cross-binutils pkgs cross-binutils-common.noarch 2.26-6.el7 epel

I wonder if a new epoch for cross-binutils-common is necessary here?
