One time I tried with glibc as patched by crosstool, to automatically  
use all the patches in your collection:
BUILD_CC=gcc CC=powerpc-750-linux-gnu-gcc AR=powerpc-750-linux-gnu-ar  
RANLIB=powerpc-750-linux-gnu-ranlib  
/build/crosstool-0.28-rc28/build/powerpc-750-linux-gnu/gcc-3.3.3-glibc 
-2.3.2/glibc-2.3.2/configure --prefix=/tools     --disable-profile  
--enable-add-ons     --with-headers=/tools/include        --without-gd  
--build=powerpc-apple-darwin7.2.0 --host=powerpc-750-linux-gnu

I'm quite sure I tried all combinations

What I found out later:
glibc-build is 488M after compiling with gcc-3.3.3 but only 198M
after compiling with gcc-3.4.1. The difference is distributed
evenly among the subdirectories. This convinces me that the problem is  
in glibc.
