Now the default startup is that the program begins at _rt0_386_$GOOS, which behaves as if calling main(argc, argv). Main jumps to _rt0_386. This makes the _rt0_386 entry match the expected semantics for the standard C "main" function, which we can now provide for use when linking against a standard C library. 386 analogue of https://golang.org/cl/7525043 R=golang-dev, r CC=golang-dev https://golang.org/cl/7551045
