CPU feature checking - require ARMv8

The packages in the isa-support family probe for microprocessor Instruction Set Architecture features such as SSE3. By refusing to install on machines lacking a required feature, they allow ISA requirements to be handled in terms of package dependencies.

This is a mostly dummy package which checks for ARMv8 and refuses to install on unsupported hardware.

ARMv8 (not to be confused with product family ARM8) introduced a large number of ISA enhancements. It is not guaranteed by the architecture baseline, but is available for newer armel machines (including CPUs that support armhf) since the Cortex-A product family, including Cortex-A32, as well as all arm64 processors. Boards include the Raspberry Pi 3 and 4.
