GCC and CLang *default* sanitizer linkage differs (static vs. dynamic). Prefer default behavior as alternate seen having issues. Default (GN)U linker fails with unresolved symbols linking Clang built binaries with sanitizer enabled. Force use LLVM linker lld for Clang builds. Sanitizer instrumentation and link flags should be retained for all binaries. Updating samples cmake configuration to keep those flags after unset logic at the ie_build_samples().
