Description of the problem

Got a python3 trusted file error when running the pytorch sgx example, see below:

ERROR: Failed to load /python3. This may be caused by the binary being non-PIE, in which case Graphene requires a specially-crafted memory layout. You can enable it by adding 'sgx.nonpie_binary = 1' to the manifest.
Makefile:184: recipe for target 'test-12-ubuntu18.04' failed
make: *** [test-12-ubuntu18.04] Error 13

Steps to reproduce

Run make test-12-ubuntu18.04 under graphene/Tools/gsc/test

I am using the latest graphene driver master branch (commit 4386dbeb1260d8743ea3a5fbe4fc5fd61322008c) and graphene master branch (commit 36ccd3ea4c957c8ad8cb92cf0ba3697a3ab90e8b) fyi.

PLEASE ENSURE THAT THE ISSUE REPRODUCES ON THE CURRENT MASTER BRANCH
