 Please try the attached patch, which makes it possible to set CC and CXX
 in make.conf, while allowing the build32 stage to still override them.
 
 Explanation:
 1) The build32 stage sets environment variables CC, CXX, AS and LD for
its sub-make, to add 32-bit specific flags (-m32 and such).
 2) The sub-make reads sys.mk, encounters CC?= and CXX?= assignments, so
does not alter them.
 3) After some other stuff, sys.mk reads /etc/make.conf. When you have
CC=xxx and CXX=yyy statements in there, they will *override* the
build32-supplied CC/CXX values, nullifying the 32-bit specific flags.
 4) Thus all objects get built as 64-bit anyway, and since LD is usually
not set in make.conf, it still has the 32-bit flags!
 5) Now, whenever something is linked, you will get a ld: Relocatable
linking with relocations from format elf64-x86-64-freebsd (foo.o) to
format elf32-i386-freebsd (bar.o) is not supported error.
 
 The patch fixes this by adding -ECC -ECXX -EAS -ELD to the build32
 sub-make invocation, which forces those environment variables to always
 override any assignment in makefiles.
 
 It makes it possible to simply do:
 
 CC=clang
 CXX=clang++
 
 in your make.conf, or specify a path, even:
 
 CC=/usr/local/bin/gcc46
 CXX=/usr/local/bin/g++46
 
 Note this was already possible on i386, but not yet on amd64.  Also,
 strange things might happen if you set CC but not CXX, or vice versa...

any chance this patch can be committed?

cheers.

I hope so, but it needs to be reviewed by one or more senior build
gurus, before it makes a chance (if any) to get into 9.0-R.

It's really just a band-aid now.  Obviously, the whole way Makefile.inc1
sets up CC to run the build32 stage should be overhauled, and as Warner
said, we really need a (SYSTEM|WORLD|PORTS)_COMPILER global switch
(instead of manually setting CC), but that kind of restructuring must be
done after the tree is unfrozen, not now.

 Most likely, this is because you are forcing CC=clang, which does not
 work as expected.  Can you please post your /etc/make.conf and
 /etc/src.conf files, and show us any environment variables related to
 buildworld?  Also, how exactly are you running make buildworld?
 
 i've attached my src.conf, my make.conf and the output of 'env'. nothing

 The problem is in your make.conf. Effectively, you are doing:

The problem is in your make.conf. Effectively, you are doing:

CC = clang
CXX = clang++

which will not work, at least not for the 32-bit compat stage on amd64.
Please use the following fragment instead, which is recommended on
http://wiki.freebsd.org/BuildingFreeBSDWithClang:
