Hi Dick (and everybody),

please have a look at the top of page 26 in 'Building TeX Live (2015)',
i.e., texmf-dist/doc/texlive/tlbuild/tlbuild.pdf.

The recommended way to build for 32 bit on a system with a 64 bit capable
compiler is, in your case

   ./Build --build=i686-apple-darwin9 CC='gcc -m32' CXX='g++ -m32' \
           OBJCXX='g++ -m32'

Or you could replace '-m32' by, e.g., '-arch i386'.
