/toolkit# ./pkgscripts/PkgCreate.py -p armada38x -v 6.1 -x 0 minimalPkg

The problem is that when ./EnvDeploy -v 6.1 -p armada38x finished running, there's a symbolic link in /toolkit/build_env/ds.armada38x-6.1

lrwxrwxrwx   1 root root     13 jul 15 18:47 pkgscripts -> pkgscripts-ng

Instead, it should be

lrwxrwxrwx   1 root root     13 jul 15 18:47 pkgscripts-ng -> pkgscripts
