This is of little practical consequence unless someone really wants to pass a 2 MB command line to a program... but as a curiosity, I ran a diff of a Koji build log from last year against a build from this year, and I noticed something odd in the configure spew.
Old build log: checking the maximum length of command line arguments... 1966080
New build log: checking the maximum length of command line arguments... 1572864
Anyone know why this got smaller? It's 1572864 on my F20 machine as well.
I don't know the answer to your question, but I found quite a good summary of all the possible issues with command line argument max length here:
