If possible, we should remove the llvm-doc component, and only ship manpages (which are part of the main llvm package), but not HTML docs. The LLVM HTML documentation is available online, and I believe it is very unlikely that anybody is using the packaged documentation.

Building the documentation has some overhead:

• We carry a RHEL-only cmake patch to remove the myst_parser dependency.
• The big-merge branch carries a patch to allow not building the lldb docs while still building llvm docs. It also does various after-the-fact cleanup to remove other built documentation (clang, lld).
• RHEL 8 converts markdown to rst using pandoc. This is not done on RHEL 9 / 10, and I'm not sure why, because I'd expect it to be necessary there as well. It's possible that building the markdown pages just doesn't work there.

It would be ideal if we could drop the llvm-doc subpackage (marked obsoleted by the main package) in all RHEL versions.
