Cross-compilation for constrained ARM environments

I prepared tools for a hardened ARM environment that lacked standard utilities and a local development toolchain. Cross-compilation let me build them on a separate machine.

The target’s architecture, ABI and libraries determine how the tools must be built. A successful build still needs runtime testing on the target, within the authorized scope and its operational constraints.

The guide shares the build approach and recipes without disclosing a client’s internal configuration.
