Since we are discussing configure lines, I do:
$ ./configure --cc='gcc -m32'
It is shorter and I believe some things are tested in configure that
are skipped with --enable-cross-compile.

My local version of gcc-4.3.6 was compiled with "--prefix=/usr/local/gcc-4.3.6"
so I use the following configure line:
$ ./configure --cc='/usr/local/gcc-4.3.6/bin/gcc -m32'
