CPU feature checking - require ARMv8CRC

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 ARMv8CRC and refuses to install on unsupported hardware.

CRC32 instruction performs a cyclic redundancy check (CRC) calculation on a value held in a general-purpose register.

It is available on most ARMv8 processor.
