It was required and used for EL7 (and lower?) only.
EL8 comes with gcc-8.5 which suppports c++17. However, the standard filesystem library is supposed to be linked separately on it. While we can do some changes to OpenModelica configurations to specifically support EL8 with its gcc-8.5 setup, it seems easier and reasonable to just require gcc-11 like we do for EL7.
