Currently, on darwin, we only support cgo_dynamic_import for functions, but not variables, as we don't need it before. mach_task_self_ is a variable defined in the system library, which can be used to e.g. access the process's memory mappings via the mach API. The C header defines a macro mach_task_self(), which refers to the variable. To use mach_task_self_ (in pure-Go programs) we need to access it in Go. This CL handles cgo_dynamic_import for variables in the linker, loading its address via the GOT. (Currently only on Darwin, as we only need it there.) For #50891.
