	In external linking mode, allow unresolved references to
	<local> in the go.o object file prepared for the host linker,
	under the assumption that <local> will be supplied by the
	other object files that will be linked with go.o.

	Example:
	//go:cgo_import_static puts_wrapper

//go:cgo_export_static <local> <remote>

	In external linking mode, put the Go symbol

preserving the behavior of earlier versions of Go.
A future version of Go may change the defaults to
`tarinsecurepath=0` and `zipinsecurepath=0`.

Go 1.20 introduced automatic seeding of the
[`math/rand`](/pkg/math/rand) global random number generator,
controlled by the [`randautoseed` setting](/pkg/math/rand/#Seed).

Go 1.20 introduced the concept of fallback roots for use during certificate verification,
