Before llvm4, both major and minor version updates of llvm were regularly breaking API. Because of that, the libLLVM library was named in following format: libLLVM-${major}-${minor}.so (https://bugs.llvm.org/show_bug.cgi?id=25059) (https://reviews.llvm.org/D13841) The package containing this library was called libLLVM${major}_${minor} which follows our guidelines. Since llvm4, llvm decided to follow semantic versioning and only break API if the major version was increased. In addition they do not intend to ever have minor version other than 0. (http://blog.llvm.org/2016/12/llvms-new-versioning-scheme.html) The package was renamed to libLLVM${major}, which no longer follows the naming guidelines, but since the package contained multiple libraries, it was not detected. Since bnc#1049703 the libLLVM${major} package contains only the libLLVM-${major}-${minor}.so library and no others. This triggers the shlib-policy-name-error check in our packaging system. Because the reasons for using the libLLVM-${major}-${minor}.so format are no longer valid, lets revert back to libLLVM.so.${major}.${minor}.${version} format. That way the package name matches our guidelines.
