Comment (by fhgwright):

 You misunderstood.  The problem isn't that `clang` is being used by
 mistake; the problem (I think) is that it ''needs'' to use `clang` and
 can't, which is why I was able to bully it through by forcing a MacPorts
 `clang` on the command line.

 I have no idea why the problem only shows up on 10.5/i386/Xcode3.1.4, but
 it does.  I think this block is relevant:
 {{{
 # Older versions of cctools have a history of being problematic with
 complex
 # asm like libffi has, so opt for the integrated assembler if it's
 available
 if {[string match *clang* ${configure.compiler}]} {
     configure.cflags-append -integrated-as
 }
 }}}

 Forcing it to use `clang` allows this to have an effect.  It then rebuilds
 `llvm`, due to the dependency which is only "loosely circular".

 I'll attach the logfile.
