Yes, that's right. Which means they should preferably be defined
in the IDL_STARTUP file. There is one way of getting around this,
though. In your case, write

dummy = execute("endian = !little_endian")
return,endian

instead of simply return,!little_endian. This will allow your
routine to compile, and define the system variable before it's
used.
