Make build hermetic without shell scripts
- Fix some minor issues in ar.com - Have execve() look for `ape` command - Rewrite NT paths using /c/ rather /??/c:/ - Replace broken GCC symlinks with .sym files - Rewrite $PATH environment variables on startup - Make $(APE_NO_MODIFY_SELF) the default bootloader - Add all build command dependencies to build/bootstrap - Get the repository mostly building from source on non-Linux
