I'm guessing no.
Gladiator stacks with a bunch, for example Brawler (archetype not alt class), Crossbowman, Shielded Fighter, Sword Lord.
That was from just a quick look at the table presented on the pfsrd website.
Armor master is compatible with Dawnflower Dervish. Not terribly effective, though.
There are probably others, but viewing the tables is difficult on this phone.
Off the top of my head, Gladiator mixes with a few, and so does the Squire archetype.
Yeah, not terribly USEFUL mixes, but they exist.
