Individual skill
cross-gcc
Use when compiling for ARM, AArch64, RISC-V, or MIPS from x86-64 with a GCC cross toolchain: triplets, sysroots, pkg-config, CMake toolchain files, QEMU. Not for Zig: use zig-cross.

# Cross-compilation with GCC
## Contract
| Field | Bound contract |
|---|---|
| Trigger | The user needs to build for a different architecture with a `<triplet>-gcc` toolchain, gets `Exec format error` or `wrong ELF class`, finds host libraries leaking into a cross link, or wants to run and debug a cross-built binary under QEMU. |
| Authority | Read-only. The skill emits install commands, compiler invocations, environment settings, and a toolchain file to chat; the user runs them. Rollback is not needed. No remote mutation. |
| Side effect | Chat output. Confirmation compiles run on scratch files. |
| Done | The triplet, toolchain, sysroot, and build-system wiring are stated for the target, every flag is confirmed against the GCC target-options documentation or the installed cross compiler, and each error in the request has a cause and fix. |
## Inputs
- Target: required. Architecture, OS or bare metal, ABI, and CPU when known.
