I'd recommend keeping build_arch at x86_64, and setting universal_archs to i386 x86_64 (should already be set that way) and then building ports with the +universal variant.

However, setting build_arch i386 should have worked and you should not have encountered an error

This kind of thing has appeared often; you can search the issue tracker. I don't remember what the ultimate solution turned out to be, or if there even was one.
