Then it's something that's happening in the buildworld framework.
You might have some weirder stuff in /etc/make.conf, or /etc/src.conf.
The src.conf stuff would affect your buildworld capabilities.

If I remember correctly, cc1 is the name of the temporary compiler (it's
gcc) built in /usr/obj. buildworld builds gcc, and uses that copy of
gcc to compile world, rather than /usr/bin/gcc.

I can't explain what's going on here. I don't have this problem.
FWIW, there's some historic reports of this kind of issue, with
different issues. Some are due to users dotfiles, others are due to
mixed gcc versions on the system (users trying to use gcc 3.4 with gcc
4.x flags like -Wno-pointer-sign), and others are due to CFLAGS
modifications.
