Look at the preprocessor definitions for each configuration to see what the differences are. Essentially, what you're seeing is that some configurations have reduced functionality in order to decease the code size of the bootloader, which doesn't need everything. The app always uses the fully functional configuration, which is the OTG for the IOIO OTG, and the unqualified for the IOIO v1, which doesn't support OTG.
