Well sort of … We are only using arm64 as a configure option to enable building
the unified ARM32/64 port and a label in Jira to identify which port a bug or RFE is related to.
Both 64-bit ARM ports have been using aarch64 for the os.name property
since day one and I think we should stick to this name in the release file to
avoid any confusion.
