go/src/runtime/rt0_android_arm.s
Srdjan Petrovic d1eee2cebf runtime: shared library init support for android/arm.
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.
