The libstdc++ copy trick is no longer needed, as noted in PR #931
which removed it for manylinux2014-aarch64.

-# DESCRIPTION: This file is invoked two times. first time from Makefile with
-#              PASS == 1 and second time in Dockerfile.in with PASS == 2. In
-#              dockcross container, the current libstdc++ is not the same as
-#              in manylinux containers. So, copying the libstdc++ form manylinux
-#              container to dockcross container. It is being done int 2 pass.
-#              during PASS == 1, the script will copy libstdc++ from manylinux
-#              container to build machine and then during PASS == 2, libstdc++
-#              will be copied from build machine to dockcross container
