Build Clang++20 (LLVM 18 and lldb) from source

[@guilherme5094]

Thanks again Mike, I've been using Clang for a while now and really like it, especially the error messages.

[@MikeShah]

Cheers! I think it's been great to have both clang and gcc, they constantly push each other to improve on things -- especially error messages! (Clang fixits can also be quite nice!)

The advantage of being an Arch user at 2:25 is that my GCC/Clang is very, very fresh. Pacman wins again!

i built on x86 machine fedora for the multiple targets as cross compiler when i compile the c program during the linking stage it is not able to find libc.a and libm.a and other few libraries how to resolve this

[@MikeShah]

Hmm, I haven't built on Fedora. Perhaps need a full host build? libc.llvm.org/full_host_build.html

I would be interested in seeing how this could be done on Windows.
