make/module.mk: Trigger module rebuild on ARCH changes

Before aosp/3527960, vm-x86_64-test_os built arm64 targets. Unfortunately, the
change does not trigger a full rebuild but causes the incremental build to fail.

This change introduces a dependency on rust module config to a ARCH variable
to detect ARCH change during incremental build.

Bug: 399565091
Test: build.py vm-x86_64-test_os-userdebug

LK

The LK embedded kernel. An SMP-aware kernel designed for small systems.

See https://github.com/littlekernel/lk for the latest version.

See https://github.com/littlekernel/lk/wiki for documentation.

Builds

Build Status

To build and test for ARM on linux

  1. install or build qemu. v2.4 and above is recommended.
  2. install gcc for embedded arm (see note 1)
  3. run scripts/do-qemuarm (from the lk directory)
  4. you should see ‘welcome to lk/MP’

This will get you a interactive prompt into LK which is running in qemu arm machine ‘virt’ emulation. type ‘help’ for commands.

note 1: for ubuntu: sudo apt-get install gcc-arm-none-eabi or fetch a prebuilt toolchain from http://newos.org/toolchains/arm-eabi-5.3.0-Linux-x86_64.tar.xz
