Since LLVM 20, libcxx shares some of its low-level implementation with libc, thus requiring libc.

I'm not sure what shinchiro was thinking, but updating LLVM is not as simple as just switching branches.

Oh no..previous LLVM is easy to upgrade. Revert for now since I dont have time to deal with this shit
