// Architecture-specific code lives in cmd/link/internal/GOARCH.
//
// Program initialization:
//
// Before any argument parsing is done, the Init function of relevant
// architecture package is called. The only job done in Init is
// configuration of the architecture-specific variables.
//
// Then control flow passes to ld.Main, which parses flags, makes
// some configuration decisions, and then gives the architecture
// packages a second chance to modify the linker's configuration
// via the ld.Arch.Archinit function.
