It's a reminder from the good old days that these were flat files loaded 
by kvmctl.

I'll rename them in a later patch.  .elf32 isn't a good name either, it 
implies 32-bit execution, whereas it's just the file format due to 
multiboot constraints.  Maybe .test (and .test32 and .test64 when we 
build both).
