To detect when an object file is build with the Branch Target Identification (BTI) and Pointer Authentication Code (PAC) extensions there is an elf note the compiler will insert. It will only do so from a high level language, e.g. C or C++. To get the not in assembly add the GNU_PROPERTY_AARCH64_FEATURE_1_NOTE macro that can be used to create it, and the GNU_PROPERTY_AARCH64_FEATURE_1_VAL macro to insert the correct value based on which combination of BTI and PAC are enabled.
