tools/clang/codesearch: support building with make
Currently, clang tools are built by copying their code into a
llvm-project repository and adding build rule to LLVM's CMake. This
allows pinning a specific LLVM hash which is convenient but it's also a
bit painful to copy code across repositories.
This adds a rule to make that can build syz-codesearch with a simple g++
invocation that uses llvm-config to get the LLVM compiler and linker
flags and hardcodes some clang libraries to link against since I could
not find a better way. (llvm-config does not have "components" for
clang)
