Some distros, including Ubuntu/Debian, don't provide a "python"
command unless an additional package is installed. Using "python3"
explicitly should work everywhere.
Using "/usr/bin/env" respects the user's PATH, so they can choose
a specific Python version instead of forcing the systemwide copy.

You'll need a libgcc build with interworking enabled (our eabi gcc works)
Confirmed to work on Sansa AMS
Confirmed to boot on Gigabeat S
Not working on PP, linker generates invalid branches when mixing
ARM->thumb switches and long calls
Build time will be about 50% longer, because the gcc wrapper script
tries to build everything with -mthumb and falls back to default if it
fails (for example if the file uses inline ARM-only assembly)
