dalvikvm builds and prints version info

With some additional trickery, we can get up to the point where dalvik
tries to run dexopt to optimize our dex file:

root@KaisTouchPad:/media/cryptofs/apps/usr/palm/applications# ANDROID_DATA=/media/internal LD_LIBRARY_PATH=com.kai.dalvikvm/lib ./com.kai.dalvikvm/bin/dalvikvm -Xbootclasspath:$PWD/com.kai.dalvikvm
/framework/core.jar -classpath ./com.kai.dalvikvm/CmdLine.jar
W/dalvikvm(16453): ANDROID_ROOT not set, defaulting to /system
E/dalvikvm(16453): execv '/system/bin/dexopt' failed: No such file or directory
W/dalvikvm(16452): DexOpt: --- END 'CmdLine.jar' --- status=0x0100, process failed
E/dalvikvm(16452): Unable to extract+optimize DEX from './com.kai.dalvikvm/CmdLine.jar'
Dalvik VM requires a class name
