Expand description

This macro tests, at runtime, whether an aarch64 feature is enabled on aarch64 platforms. Currently most features are only supported on linux-based platforms.

This macro takes one argument which is a string literal of the feature being tested for. The feature names are mostly taken from their FEAT_* definitions in the ARM Architecture Reference Manual.
