Wait. I also have an xml2-config in my /usr/bin (and it's not a
symlink). Not sure how it got there, though. I'm also using Mac OS X
Snow Leopard. Do you have that file in /usr/bin?

I guess the way to go in this case would be to compile the object files
with -arch i386 and -arch x86_64 separately and then link them together
using lipo. Never tried that, though. The options that you mentioned are
related to the generation of dependency rules in the makefile, so we
can't really get rid of them without switching to a completely different
build system.
