Internal and External Linking

The text above describes "internal" linking, in which cmd/link parses and
links host object files (ELF, Mach-O, PE, and so on) into the final
executable itself. Keeping cmd/link simple means we cannot possibly
implement the full semantics of the host linker, so the kinds of
objects that can be linked directly into the binary is limited (other
