Follows http://golang.org/cl/8454, a similar CL for arm architectures. This CL involves android-specific changes, namely, synthesizing argv/auxv, as android doesn't provide those to the init functions. This code is based on crawshaw@ android code in golang.org/x/mobile. Change-Id: I32364efbb2662e80270a99bd7dfb1d0421b5417d Reviewed-on: https://go-review.googlesource.com/8457 Reviewed-by: David Crawshaw <crawshaw@golang.org>
