cmd/link/internal: thread *ld.Link through calls 

Ctxt is a global defined in cmd/link/internal/ld of type *ld.Link.
Start threading a *ld.Link through function calls instead of
relying on the global variable.

Ctxt is still used as a global by the architecture-specific packages,
but I plan to fix that in a subsequent CL.
