LLVM 23 removed the standalone build mode for openmp, so do_configure
fails with

  The legacy standalone build mode has been removed

Configure it through the runtimes build with LLVM_ENABLE_RUNTIMES=openmp,
the same way libcxx is built.

The runtimes build reads LLVM_LIBDIR_SUFFIX; nothing in LLVM 23 reads
OPENMP_LIBDIR_SUFFIX any more, so pass the standard variable like the
other clang-family recipes do. Without it openmp installs into lib/
while a multilib configuration packages lib64/, and do_package fails
with "installed but not shipped" for libomp.so, libarcher.so,
libompd.so and the cmake files.
