Review comment:
What we need here is to turn a link file to a regular file, instead of
finding the path to the regular file. It's a different thing. Jenkins can't
wrapper a link file and mxnet wants a library file named libmkldnn.so.0,
instead of libmkldnn.so.0.13 (which is what libmkldnn.so.0 points to). If what
you find can turn libmkldnn.so.0 (a link file) to a regular file with the same
name with a single command, can you please provide the command?
