让Android adb运行在ARM平台上

对android/system/core中的adb打上如下补丁：

From e8853dc01a99fddd57b375c29489cd817ddebc2d Mon Sep 17 00:00:00 2001

Subject: [PATCH] adb: make adb support arm as the host and adbd/host co-exist

The Makefile is copied from https://gist.github.com/958335
with added DEFAULT_ADB_PORT=8888 to avoid the tcp port confliction
between adbd in client and cloned usb thread in host adb

adbd uses 5037 port, thread in host adb uses 8888

在adb所在目录运行make,使用arm linux toolchain得到了adb。即可以在运行ARM Linux平台的电路板或Android手机上作为adb的host了。
