 I think this is referring to the '#!' line of a script, not internal
 kernel limits.  This limitation should not affect Gnu Make recipes.

Well, the #! limit is a kernel limit too. But your point that it shouldn't affect GNU make recipes (directly) is a good one since make invokes recipes via "/bin/sh -c recipe" without ever using a shebang. I have to admit I'm a little lost on where the shebang limit is coming in here but it does seem to be somehow.
