2. caliper fails when apply a patch for the aarch64 architecture in spack

@rfhaque where is the PR checklist template? Those are helpful for reviewing. In particular, for adding a new system, we also need:
{ } Add a human-readable system description to systems/all_system_definitions
{ } Verify info added in all_system_definitions generates a new system column in Catalogue/System Specifications (https://software.llnl.gov/benchpark/system-list.html)
{ } Add a dry run of an existing benchmark using the new system definition

(@slabasan, if those are not listed in the PR template right now, we probably want to add them)

@rfhaque What is different about this spack package from upstream? We need to work with @dbo to review/upstream it.
