llvm16/openmp-drop-rpath.patch
Aaron Puchert e16eeb0094 - Apply clang-shlib-symbol-versioning.patch to add symbol versions
to libclang-cpp.so similar to libLLVM.so. This is required when
  multiple versions of the library are loaded into the same
  process. (boo#1219405, boo#1221183, boo#1233220)
- Require libffi when we build openmp for offloading.
- Correct target name for libomptarget in file list.
- Update llvm16.keyring from upstream.

Subject: [PATCH] Revert D118493 "Set rpath on openmp executables"
This reverts commit 9b9d08111b618d74574ba03e5cc3d752ecc56f55.
(Accepted by Jon https://reviews.llvm.org/D118493#4178250)
libc++, libc++abi, libunwind, and compiler-rt don't add the extra DT_RUNPATH,
it's strange for OpenMP to diverge.
Some build systems want to handle DT_RUNPATH themselves (e.g.
CMAKE_INSTALL_RPATH). Some distributions (e.g. Fedora) have policies against
DT_RUNPATH and the default DT_RUNPATH for OpenMP is causing trouble.
For users who don't want to specify rpath by themselves,
https://clang.llvm.org/docs/UsersManual.html#configuration-files
can be used to specify the default rpath, e.g.
specify -frtlib-add-rpath or -Wl,-rpath in bin/clang.cfg
