The commit 4904c4c "package/opencv3: use BR2_TOOLCHAIN_HAS_LIBATOMIC" overrides CMAKE_CXX_FLAGS with the single -latomic, losing all ABI CFLAGS that are passed there by default. This breaks build on xtensa where ABI CFLAGS contain important code generation options. Append $(TARGET_CXXFLAGS) to CMAKE_CXX_FLAGS along with -latomic.
