- update parallel_devel patch
    
    Note: tweaks to KdeLibsLibraryDependencies.cmake and/or KdeLibsLibraryDependencies-release.cmake may also be needed. Looking at those files, they seem to link the library by the fully-versioned path or by the soname, if that's true, no fixes are needed (because those aren't moved out of the way, only the .so symlinks are).
