build android adb for windows

http://source.android.com/source/downloading.html

note that checkout specific branch will make you downloading fast.

I used below command

 $ repo init -u https://android.googlesource.com/platform/manifest -b android-4.2.2_r1
$ repo -j10 sync

download complete, u should compiler the adb for Linux first

make -j4 acp adb showcommands

finish building Linux adb and then u can build for windows.

make -j4 USE_MINGW=y adb
