   Have a look at configure.ac. You need to be familiar with shell scripting, and you need to figure out a way to detect arm32 support. The autoconf documentation may be useful. (https://www.gnu.org/software/autoconf/)

    At least in CMake-based build system, it seems worth making the SECP256K1_ASM option actually dependent on the value of the CMAKE_SYSTEM_PROCESSOR variable. Then ON/OFF values will be enough for it with defaults as follows:

    • ON for x86_64
    • OFF for arm
