The problem appears to have to do with Peter's changes to procfs:
The procfs source files now include opt_compat.h, which is not
available by default when building with MODULES_WITH_WORLD set.
The attached patch seems to fix the problem in the conventional
way. However, I'm unsure which COMPAT_* options are really needed
to the procfs module. COMPAT_43 should be enough according to my
quick examining /sys/fs/procfs.
