parts of #12
This PR updates the LLVM/Clang build configuration to disable several optional components, following the build configuration used in TinyGo.
The goal is to simplify the prebuilt distribution, reduce build time, and remove unnecessary dependencies.
Disabled options and their effects
-DLLVM_ENABLE_TERMINFO=OFF
Disable terminfo support (no dependency on ncurses).
-DLLVM_ENABLE_ZSTD=OFF
Disable zstd compression support (compressed debug info and caches won’t use zstd).
-DLLVM_ENABLE_Z3_SOLVER=OFF
Disable Z3 SMT solver integration (LLVM passes/tools depending on Z3 are unavailable).
-DLLVM_ENABLE_OCAMLDOC=OFF
Skip generating documentation for LLVM’s OCaml bindings.
-DLLVM_ENABLE_LIBXML2=OFF
Disable libxml2 support (affects some parsing and AST export features).
-DLLVM_TOOL_CLANG_TOOLS_EXTRA_BUILD=OFF
Skip building clang extra tools (e.g. clang-tidy, clang-format, clangd).
-DCLANG_ENABLE_ARCMT=OFF
Disable the ARC Migration Tool (Objective-C automatic reference counting migration).
