Added config to use the external zlib for the orion Intel build. #9

Conversation

This PR adds configuration for building spack-stack on Orion using Intel compiler/mpi that forces spack-stack to use the external zlib instead of the spack built zlib-ng package. This is part of the solution for the issue with the Intel build on Orion breaking the system tar command.

The final part of the solution is to use the cmake builtin tar feature instead of the system tar command to unpack the CRTM test data (which is where the system tar command crashes).

Partially addresses JCSDA/issues/1355

I suggest we make this change across the board on Orion (for all compilers)? That would be in the Orion site config packages.yaml file.

so that both gcc and intel builds will use the external zlib package.

@climbfuji I have done as you suggested - moved the external zlib config from packages_intel.yaml to packages.yaml. I verified that I get the exact same concretization as before for intel and now get an external zlib in the gcc concretization.
