       Note: two of the dx tests (the two tests for the merger) run the command
       "dalvik" and expect it to be a working dalvik virtual machine.
       Fulfilling this expectation is no easy task.  Here's how I did it.

       - Be on Linux (Dalvik doesn't build for Mac).
       - Check out Android (I used ICS because I had it lying around).
       - make -kj25 dalvik-host
       - If you built on a remote machine, rsync "out" to where you are
         developing Buck, inside of a dedicated directory called "android"
         or something.
       - Edit android/out/host/linux-x86/dalvik to change the log tags to
         "*:w", because a spurious info message was messing up the test.
       - Delete android/out/host/linux-x86/dx so the tests will use our dx.
       - Run this rule as
         ANDROID_BUILD_TOP=/path/to/android PATH=$PATH:$ANDROID_BUILD_TOP/out/host/linux-x86/bin ant dx-tests

            This is the recommended way to link to Android's Javadoc.
            This problem derives from Android's refusal to publish the package-list file
            with their Javadoc: http://stackoverflow.com/a/2823592/396304.

            Surprisingly, the generated Javadoc does link to http://d.android.com/
            rather than a local file:/// URI that points to the local $ANDROID_HOME.

          <link offline="true" href="http://d.android.com/reference" packagelistLoc="${env.ANDROID_HOME}/docs/reference"/>
