This commit introduces a comprehensive cabal-based build infrastructure to support multi-target and cross-compilation scenarios for GHC. The new build system provides a clean separation between different build stages and better modularity for toolchain components. Key changes: - Add Makefile with stage1, stage2, and stage3 build targets - Create separate cabal.project files for each build stage - Update configure.ac for new build system requirements - Adapt hie.yaml to support cabal-based builds - Update GitHub CI workflow for new build process Build stages explained: - Stage 1: Bootstrap compiler built with system GHC - Stage 2: Intermediate compiler built with Stage 1 - Stage 3: Final compiler built with Stage 2 (for validation) This modular approach enables: - Clean cross-compilation support - Better dependency management - Simplified build process for different targets - Improved build reproducibility Contributors: - Andrea Bedini: Build system design and Makefile implementation - Moritz Angermann: Cross-compilation infrastructure The new build system maintains compatibility with existing workflows while providing a more maintainable foundation for future enhancements.
