In addition the ld.so.conf.d file is also renamed to follow the shared lib version to make it possible to install multiple versions of the shared lib.- Rebase SHERPA-MC-no-return-in-non-void-function.patch and add fixes for one more function showing the same issue in version 2.2.4.- GCC >= 6.0 required, build fails with older GCC for openSUSE <= 1320.
