readme:lld-17 download on linux

[luoliwoshang]

Fix #336
brew installs LLVM with its own lld

brew install llvm@17
❯ which ld.lld 
/opt/homebrew/opt/llvm@17/bin/ld.lld

However, apt-get install --no-install-recommends llvm-17-dev does not carry this lld，additional downloads are required, Otherwise, the #336 problem will occur
