Grow the Montauk libc enough to cross-build binutils 2.43.1 with --host=x86_64-montauk. gas, ld, ar, nm, objcopy, objdump, readelf, ranlib, strip and friends now link as native ET_EXEC Montauk binaries (staged stripped in toolchain/native/, not yet shipped in the image). New libc surface: full Linux errno and signal sets, O_* flags with real O_EXCL/O_APPEND semantics, unlink/rmdir/dup/dup2/getpid/_exit, kill (SYS_KILL), fcntl, fileno/fdopen, putc/getchar/rewind, ctime/asctime, strtoll/strtoull/atoll, bsearch, mkstemp/mktemp, realpath (lexical, drive-prefix aware), mbstowcs/mblen, chmod/fchmod/ umask/utime no-ops (VFS has no modes or settable times), full struct stat with fake inodes, sscanf field widths (bounded conversions), SCN*/PRI* completions, wait/waitpid over SYS_WAITPID, and new headers sys/wait.h, sys/param.h, utime.h, wchar.h, memory.h. fork/exec/pipe are declared but fail with ENOSYS: binutils never spawns, and real process plumbing is the posix_spawn milestone, which needs kernel support (exit status reporting, fd redirection). TCC's montauk_compat.h shims (unlink, chmod, execvp, realpath, fdopen, strtoll, strtoull) are retired in favor of the libc versions. Co-Authored-By: Claude Fable 5 <[email protected]>
