Possible linking issue with 12.0.0-rc4

Hello everyone

I believe there’s a tiny issue with the current rc4 build regarding the LLVM-C api. This is an issue I should have been more vocal about when I noticed it last week. Would be tagging the bug as blocking for 12.0.0 correct? The details are outlined in https://bugs.llvm.org/show_bug.cgi?id=49745 but to be precise, there were two typos in the new LLVM-C OrcJIT V2 bindings which would lead to linking errors upon usage.

Lang Hames and I patched the bug in https://reviews.llvm.org/D99478. I am new to all of this so I am unsure of how you usually go about solving this, but I think this commit should be included in the release to prevent the build from failing when using the new Orc APIs.

Thanks, and again, my apologies for not reaching out earlier.
