Add build-montauk-toolchain.sh: builds an OS-aware cross GCC/binutils (same versions and prefix as the bare-metal x86_64-elf toolchain) whose x86_64-montauk target links static ET_EXEC binaries against the Montauk libc sysroot with no special flags: 4 KiB max page size for the kernel ELF loader, -mno-red-zone by default, crt1/crti/crtn + -lc from the sysroot, __montauk__ defined. Target patches are checked into toolchain/patches/, the GCC target header into toolchain/files/. sys/types.h now includes <stdint.h> so hosted code (libgcov and friends) sees intptr_t via the stdio include chain.
