Build Java benchmark class, APK, and jar files.
The script will automatically attempt to build the APK if the \`dx\` command is
available in the PATH.
Output files are produced in $DIR_BUILD.
Options:
-h Show this help message.
-t Build for the target. Requires building from an Android environment.
-v Verbose. Print the commands executed.
-W Do not treat build warnings as errors.
