In essence, the _cgo_import.o file includes the extra linking
directives that cmd/link is not sophisticated enough to derive from _all.o
on its own. Similarly, the _all.o uses dynamic references to real
system object code because cmd/link is not sophisticated enough to process
the real code.

The main benefits of this system are that cmd/link remains relatively simple
