There are few problems in current recipe: (1) Observed that we need to invoke native llvm-config from target sysroot to list LLVM libraries.
clang already provides crossscripts/llvm-config, which does the job. LLVM_TOOLS_BINARY_DIR points to target sysroot but interestingly does not allow to pick llvm-config from target recipe-sysroot/usr/bin/crossscripts/ So removing LLVM_TOOLS_BINARY_DIR from search path for llvm-config. (2) Error: ispc/1.19.0-r0/recipe-sysroot-native/usr/bin/x86_64-poky-linux/x86_64-poky-linux-ld: ispc/1.19.0-r0/recipe-sysroot-native/usr/lib/libclang-cpp.so: undefined reference to `std::condition_variable::wait(std::unique_lock<std::mutex>&)@GLIBCXX_3.4.30' error: linker command failed with exit code 1 (use -v to see invocation) Currently native libraries were being linked to target build wrongly, which causes above failure. After having proper DEPENDS and setting native tools path, it fixes the issues. Drop un-needed RDEPENDS.
