  <summary>Recommended update for llvm7</summary>
  <description>This update for llvm7 fixes the following issues:

- Backport fixes and changes from Factory. (bsc#1197775)
- Drop RUNPATH from packaged binaries, instead set LD_LIBRARY_PATH for building and testing to simulate behavior of 
  actual package.
- Fix build with linux-glibc-devel 5.13.
