+Allow clang to be found in target sysroot for target builds and dont try

+Subject: [PATCH 2/2] Request native clang only when cross-compiling (#464)
+
+* Request native clang only when cross-compiling
+
+LLVM_USE_HOST_TOOLS may be set if LLVM is configured with
+LLVM_OPTIMIZED_TABLEGEN, which does not necessarily indicate
+cross-compilation or that clang will only execute on the target.
+
+By checking that CMAKE_CROSSCOMPILING is set, we ensure that we only
+build/use clang again if necessary for host execution.
+
+* fixup: CMAKE_CROSSCOMPILING implies LLVM_USE_HOST_TOOLS
+
+Co-authored-by: Wenju He <wenju.he@intel.com>
+
+* fixup: also use CMAKE_CROSSCOMPILING in top-level CMakeLists.txt
