   This PR addresses issue #1751 by adding a call to check_arm32_assembly() by default, matching the current behavior with check_x86_64_assembly().

   This would result in speedup on field_10x26_impl.h on default builds. For example, currently, the Bitcoin Core reference implementation compiles libsecp256k1 with default options, leading to unoptimal builds.

   Please provide benchmarks to support this statement.

   will do. I’m buying a raspberry PI right now. I reckon if the benchmarks don’t show improvements we should delete field_10x26_arm.s entirely

    Perhaps convert this to a draft while the CI is red?
