There haven't been any changes to src/lib/csu/i386-elf in 2-4 years:

http://www.freebsd.org/cgi/cvsweb.cgi/src/lib/csu/i386-elf/

I'm willing to bet that the compiler tinkering you've done is causing
said problem.  It would indicate whatever compiler is being used
("world-cc") is acting as if it doesn't understand the compiler flag
specified.  I can assure you that gcc does support this option.

It would be useful to see see the buildworld output with CXXFLAGS,
COPTFLAGS, CC, and CXX disabled in your make.conf.  I realise you said
"I get the same error without this stuf", but you should've sent *that*
buildworld output.  :-)

Also, you really should be using "?=" operators on those optimisation
flags, in case something else overrides them.  Yes, I know what the
documentation in share/examples/etc/make.conf says, but I still
recommend doing what I said.
