>Description:
I couldn't find whether FreeBSD world is expected to compile with compilers other than the system default, so I don't know if the report is applicable. I submit speculatively.

I am trying to compile world with gcc 4.3. In particular, I am looking for target-specific optimization for "geode" which is not supported before this version. This is what I do:
1) pkg_add -r gcc43
2) cd /usr/src && make clean
3) rm -rf /usr/obj/*
4) I edit /etc/make.conf and set:
CC=/usr/local/bin/gcc43
CXX=/usr/local/bin/g++43
CPUTYPE?=geode

5) make buildworld

I then tried to build the toolchain with the system's gcc, and the rest with gcc43:
1) rm -rf /usr/obj/*
2) make clean
3) make toolchain
-- so far so good --
4) I set CC, CXX, CPUTYPE in /etc/make.conf to compile the rest of the world
5) make -DNO_CLEAN everything
I get soon
