install xinit -> bsdmake: setrlimit: Invalid argument

Attempting to install xinit on PPC G5 10.5.8 produces failure in the build of tradcpp in bsdmake. Tried port clean, but still get:

BingleyG5:~ bryan$ sudo port -v install xinit
--->  Computing dependencies for xinit..........

I see a seemingly identical issue was resolved a couple of years ago in #105220. Reading some of that history, here is output of ulimit:
