This was originally written by Thomas Roth <code@stacksmashing.net> to
make it possible to support more emulators than what fits into memory at
the same time (commit c13aa09b).
Instead of generating a monolithic binary, the different emulators are
stored in flash and loaded into ram right before they are launched.
This is the basis for adding more emulators e.g. smsplusgx.
