By executing the following additional commands. catkin_make works as usual.

sudo ln -s /usr/lib/aarch64-linux-gnu/*.so  /usr/lib
sudo ln -s /usr/lib/aarch64-linux-gnu/cmake/*  /usr/lib/cmake

I tried to add some message in cmake.

message(STATUS "RT_LIBRARY: ${RT_LIBRARY}")

Before installing gcc. It shows:

RT_LIBRARY: /usr/lib/aarch64-linux-gnu/librt.so

After installing. It shows:

RT_LIBRARY: RT_LIBRARY-NOTFOUND

I think I know what's going wrong. librt.so, libthread.so(and many more) should also be linked.
