Thanks for the reply, Herbie!
Still, it is not clear to me: does XCode 2.4 build both 32-bit and
64-bit binary parts in a Universal Binary (e.g. a 4-part binary),
or there is some settings for this?
Likely better to ask on the xcode-users list then this list.
Can you clarify what do you mean by 64 bit binary? Are you talking
about one that is using LP64 (longs and pointers are 64 bit) or are
you talking about a binary that just wants to use 64 bit math
capabilities in its own code? I am going to to assume the former for
now.
You can supply "ppc" (LP32 PPC), "ppc64" (LP64 PPC), i386 (LP32 x86),
and x86_64 (LP64 x86) for ARCHS (not tried the later in Xcode 2.4
just yet).

The x86_64 binary is still limited like the ppc64 binary to linking
only against libSystem, Accelerate.framework and couple of others.
