Ah ha. That was my problem. I forgot that I ran into this with LLVM 1.4 
as well. Basically, I specified:

--with-llvmgccdir=/Users/ejones/llvm/cfrontend/ppc/llvm-gcc/bin

instead of:

--with-llvmgccdir=/Users/ejones/llvm/cfrontend/ppc/llvm-gcc

Which does make sense now. For me, the issue was that the directions 
(http://llvm.cs.uiuc.edu/docs/GettingStarted.html) were slightly 
misleading. They say:

I read this to mean "if you can execute llvm-gcc, the configure script 
will find it." However, it turns out that I needed to remove "/bin" 
from the directory I added to the PATH. This seems somewhat silly, 
since that would *not* allow me to execute llvm-gcc in my shell. I 
don't understand autoconf at all, but it seems to me that it should do 
"which llvm-gcc" then remove "/bin/llvm-gcc" from the end of that path.

Anyhow, I have it compiling now. Sorry for taking up your time,
