* configure.ac: * Makefile.am (SUBDIRS): Replace bootstrap/ with stage0, stage1, and stage2. * am/bootstrap.am: Include all files and all rules. * meta/build-env.in (GUILE_AUTO_COMPILE): Always turn off auto-compilation. Take a GUILE_BOOTSTRAP_STAGE argument, which can be stage0, stage1, stage2, or unset. Adapt the load-compiled path accordingly. * meta/uninstalled-env.in: Include .go files from stage2. * module/Makefile.am: Rework to use boostrap.am. * module/system/base/optimize.scm (available-optimizations): Punt the inlinable-exports machinery to -O2. * stage0/Makefile.am: * stage1/Makefile.am: * stage2/Makefile.am: New files.
