Phase 1 of #27 (ARM cross-compilation toolchain): synth compile --link: - New --link flag invokes arm-none-eabi-gcc after compilation - Auto-detects arm-none-eabi-gcc/ld in PATH - Generates linker script with Meld integration sections - Produces firmware.elf from module.o + kiln-builtins.a - --builtins <path> specifies the kiln-builtins object file kiln-builtins stub: - tests/integration/kiln_builtins_stub.c — minimal C implementation - __meld_dispatch_import: returns 0 for all imports (test stub) - __meld_get_memory_base: returns __wasm_memory_start linker symbol End-to-end integration test: - tests/integration/bare_metal_e2e.sh - WAT → synth compile → module.o → link → firmware.elf → validate - Skips gracefully if arm-none-eabi-gcc not in PATH Closes #27 Implements: CC-003 Implements: XC-001 Trace: skip Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
