Yes, in armv8 nomenclature this is "asimd" in /proc/cpuinfo for advanced simd extensions. Your compilers will automatically pick it up, as far as I know, as it's a base feature of Armv8.0-A I believe.
The gcc manual confirms my belief here by straight up saying +simd is default on armv8-a:

So nothing special is needed in any configure script, any build for aarch64 will use simd, though auto-vectorisation might not occur on lower optimisation levels.
