I presume you have already checked SVN HEAD, or 1.35, and the problem is still

For the record, SVN HEAD version of tools/build/v2/tools/gcc.jam has this:

        flags gcc OPTIONS <architecture>x86/<address-model>32 : -m32 ;
        flags gcc OPTIONS <architecture>x86/<address-model>64 : -m64 ;

I suspect you version might not have the first line, so if the compiler
default is 64-bit, you'd always get 64-bit binary; you might want to
add the first line to your gcc.jam
