Looks to me like, best guess, the install of constants.vams is in a race with the installdirs target. That's a little weird because it has never come up before, but when I look at the Makefile with this thought in mind, I see that it is plausible if you have a large value for the "-j" flag to make. I don't know a proper fix.
