Parallel build broken for PCKRetrievalTool

[jurobystricky]

There is a race condition in PCKRetrievalTool Makefile. On my system it is 100% reproducible.
(The build fails on less than 16 CPUs as well)
Steps to reproduce:

$ cd ~/SGXDataCenterAttestationPrimitives/tools/PCKRetrievalTool
$ make clean
$ make -j 16

Running using a single CPU works fine:

$ make clean
$ make

Edited result:

Succeed.
