Ahh, but when you ran "make universe" there were not yet any C++
things in lib/. My patch adds a C++ library, and it fails when
building the 32-bit version. Here's the actual command that failed.
I don't know why it failed, because
/scratch/tmp/asomers/obj/home/asomers/freebsd/head/lib32/usr/include/stddef.h
_does_ exist.
