A slightly more elegant way to select llvm versions

[Jerry1144]

Instead of changing Homebrew logic so it finds the llvm@12 or llvm@15, the neat way of doing this is:

ln -s ./llvm@12 /usr/local/opt/llvm

This creates a symlink to the relevant llvm@12 that Brew's build logic happily accepts.

I believe this even is the intended way of switching between llvm versions. Brew has --cc=gcc-13 for gcc@13 but never a --cc=llvm_clang-12 for llvm@12.

Anyway, many thanks for spotting the line that makes llvm builds fail.

I think it's a good idea if you don't take dependencies into account
Thank you for teaching me
