Since Make does not visit modules in topological order of their
<uses-library> dependencies, information from dependencies to the
dexpreopted module has to be passed via dexpreopt.config files. A build
rule for a dexpreopt.config file depends on dexpreopt.config files for
<uses-library> dependencies, and dex_preopt_config_merger.py script
extracts the necessary information from dependency configs and patches
the module's config.
