Current Mac OS X installs universal(?) binaries including
i386 & x86_64 codes on x86_64-capable machines by default,
and the kernel can execute both binaries. So, i386 binary
(without x86_64 code) is portable on both intel platforms.

Some frameworks have incompatibilities between i386 and
x86_64 codes (some APIs might be available on i386 only,
because for back compatibilities), so the build testing
with "-arch x86_64" flag would be safer for future development.

Do you mean an archive library of Cairo? Or, do you mean
statically linked binary linking Cairo? I think, Mac OS X
is shipped without C startup routines & library (libSystem)
for static binary, and you cannot build statically linked
binary, even hello-world. It might be possible to prepare
such files by compiling the disclosed sources of Mac OS X
SDK, but nobody can guarantee that it works well.
