Strange, it was YOUR thread on the list:
"[distcc] distcc with cc1", that helped me to figure out the scheme.

Anyway, here is my receipt:

--- Begin of LinuxPC-stuff ---

host=i686-pc-linux-gnu
target=powerpc-apple-darwin
prefix=/usr/local/$target

1. Build of gcc-3.3.2 on LinuxPC (i686-pc-linux-gnu). No probs.

2. Build of binutils-2.14 on LinuxPC. No Probs.
    $ ../binutils/configure --target=$target --prefix=$prefix
    $ make
    $ make install

3. Copy "/usr/include" from MacOS X to LinuxPC as 
"/usr/local/powerpc-apple-darwin/"
    but take care:

    $ dir /usr/include/gcc/darwin/2.95.2/g++/
    total 1232
    -r--r--r--   1 root     wheel        1049 Sep  2  2001 typeinfo
    -r--r--r--   1 root     wheel         161 Sep  2  2001 new.h
    -r--r--r--   1 root     wheel        1207 Sep  2  2001 new
    ...
    -r--r--r--   1 root     wheel       13509 Sep  2  2001 bastring.cc
    -r--r--r--   1 root     wheel        4314 Sep  2  2001 strstream.h
    lrwxr-xr-x   1 root     wheel           1 Sep  2  2001 
std -> .  <--- !!! ATTENTION !!! gets recursiv!
    -r--r--r--   1 root     wheel        2230 Sep  2  2001 _G_config.h
    drwxr-xr-x 127 root     wheel        4274 Sep  2  2001 .
    drwxr-xr-x  12 root     wheel         364 Sep  2  2001 ..

    Before copying / archiving you have to remove "std".
    Before your next compile on the Mac you have to re-link "std" again...

4. Build of gcc-3.3.2 CrossCompiler on LinuxPC. Lots of troubles.
    $ ../gcc/configure --target=$target --prefix=$prefix
      *** This configuration is not supported in the following 
subdirectories:
      target-libffi target-boehm-gc target-zlib target-libjava
     (Any other directories should still work fine.)
    $ make -k
    $ make install -k
    The "-k" was the trick. From YOUR thread I learned, that there is no 
darwin-assembler in gcc.

5. Copy the not installed "cc1", "cc1plus" "by hand".
    cd ~/YOUR-BUILD-WORKING-DIR/build-gcc-powerpc-apple-darwin/gcc
    sudo cp -p cc1 /usr/local/powerpc-apple-darwin/lib/gcc-
lib/powerpc-apple-darwin/3.3.2/
    sudo cp -p cc1plus /usr/local/powerpc-apple-darwin/lib/gcc-
lib/powerpc-apple-darwin/3.3.2/

--- End   of LinuxPC-stuff ---

--- Begin of MacOS X-stuff ---

6. I used a wrapper-script for "cc" on MacOS X.

    It is a perl-script with the following core:

    # Output CompilerCmds
    #--------------------------------------------------
    Command ("/usr/bin/cc -E $NoOutParameters $Name.$Extension > 
$Name.i\n");      # LOCAL
    Command ("powerpc-apple-darwin-gcc $NoOutParameters -S $Name.i -o 
$Name.s\n"); # DISTANT
    Command ("/usr/bin/cc $Name.s $TheParameters 
\n");                             # LOCAL
    Command ("rm $Name.i 
$Name.s\n");                                              # LOCAL
    #--------------------------------------------------
    # Output CompilerCmds

    Quick Description:
    $TheParameters:   All parameters.
    $NoOutParameters: All parameters except "-o file".
    $Name:            Source-file-name.
    The script also handles a problem with quoting of parameters.
    My test-case was the "readline-4.3" library. The Makefile generates 
lines like:
    ... -DRL_LIBRARY_VERSION='"4.3"' ...
    This is handled by the perl-script.

    If someone is interested I can post the complete script.

7. Create the necessary links.

8. For me with MacOS X 10.1.5
    DISTCC_MMAP=0 is essential.

9. Time the success:
    Local:
    (G3 / 350 MHz)
    real    1m6.498s
    user    0m48.330s
    sys     0m8.440s

    Distccd (tcp) -j 5, no "localhost"
    (Intel SuSE-Linux / 900 MHz)
    real    0m39.759s
    user    0m21.170s
    sys     0m11.380s
