While the test_suite presented in #589 does work, it is still pretty simple and can be improved and enhanced.

• Add tests for gnutils and coreutils.
• Add necessary utilities so more complex programs can be compiled from sources.
• Integrate CMake, so one could write something like make validate and the subset of test that is deemed necessary (for example everything with min t

Currently, decompilation of Windows executables produces unreadable and/or semantically wrong output because the signatures for most of the Windows API functions are missing. We should add signatures for at least the most commonly used ones.

As suggested here by @jabuzz, we could use DIP switches or jumpers for defining config settings, so that we don't have to upload suniversal to the Arduino each time we want to make a config change. A minor drawback of this is that to make the switches or jumpers accessible, you either need to put the converter into a sep
