enable CONFIG_IA32_EMULATION in kernel config

This lets us run 32-bit i386 binaries on the x86_64 kernel. See issue #8.

$ echo 'package main; func main(){println("hello world")}' > hello.go
$ GOARCH=386 GOOS=linux go build hello.go
$ scp hello $(make ip):
$ ssh $(make ip) ./hello
hello world

Hi @saljam ,
I had flown from San Jose to Japan.
I will check it out later when I get some time.
