ppcx64 will always generate code that is the equivalent of gcc -m64. For gcc -m32 code, you have to compile a ppc386 instead (bootstrap compiler is also available in the same directory). The generic compiler driver (similar to the "gcc" program for GCC) is called "fpc", and selecting the target processor happens using its -P option (-Pi386, -Px86_64). That one will call through to ppcx64, ppc386, ...
