Added explicit `libcxxrt` dependency to the `cpprt` target to ensure artifacts are available before building Removed `libcxxrt` from `$(LIBTCXX)` dependencies since it's now transitively satisfied through `cpprt` Simplified the `$(LIBCXXRT_STAMP)` rule by removing unnecessary `flock` synchronization logic --------- Signed-off-by: Lukasz Kalica <lukasz.kalica@intel.com>
