You can't do that.

  Most APIs in Mac OS X v10.5 are available to both 32-bit and 64-bit
  applications, but some APIs commonly used by Carbon applications are
  not. In particular, the APIs used to implement a Carbon user
  interface are generally available only to 32-bit applications. If
  you want to create a 64-bit application for Mac OS X, you need to
  use Cocoa to implement its user interface.

As unexmacosx.c is 64-bit compliant as of Emacs 22.2, you can build
tty-only or X11 build if you have necessary libraries.  (I've never
tried CC='gcc -m64', but CC='gcc -arch ppc64' or CC='gcc -arch x86_64'
would work.)
