needed to link programs that import package net.

Runtime

When using cgo, Go must not assume that it owns all details of the
process. In particular it needs to coordinate with C in the use of
threads and thread-local storage. The runtime package declares a few
variables:

	var (
		iscgo             bool

//
//	GOIOS_DEV_ID: The codesigning developer id or certificate identifier
//	GOIOS_APP_ID: The provisioning app id prefix. Must support wildcard app ids.
//	GOIOS_TEAM_ID: The team id that owns the app id prefix.
//
// $GOROOT/misc/ios contains a script, detect.go, that attempts to autodetect these.
