Description
OpenJDK 8u can currently not be built on AArch64 at all. As a pre-requisite to a potential inclusion of the AArch64 port, maintained separately by the AArch64 project, we should add support to at least make 8u buildable with the Zero assembler port.

As broken as it has been for years.

AArch64 Zero would be broken until JDK-8253284 is backported.

Fix Request [8u]: Add recognition of the ELF format on AArch64 so that the Zero assembler port will build there. Should not impact builds on existing architectures and allows the JDK to build on AArch64 (tested with full bootstrap by myself & Aleksey Shipilev). Patch reviewed by Aleksey (see 8u RFR link).
