BIG_ENDIAN may be defined even on little endian machines. Fix the test by checking whether LITTLE_ENDIAN is defined and if it is whether it matches the byte order.
This allows writing a program which uses stdin/stdout as a simple protocol to emulate a device towards a virtual driver in userspace.

The implementation expects messages to be send to and read from stdin/stdout. It may be used to emulate an extremely dumb fingerprint device for testing purposes. This is intended to be used by libfprint. This is work-in-progress!

I wanted to mock a simple device, so started to add code to do so.
This is work in progress, I'll probably shuffle things around a lot. But, input on the approach is welcome and maybe it is useful to someone other than me.
