You need the headers from glibc, I think.
There are circular dependencies between gcc and glibc that are hard to satisfy.
Perhaps you should try crosstool; it's an updated version of Bill Gatliff's
script, and takes care of all the circular dependencies.
You can download the crosstool script at
   http://kegel.com/crosstool
And as you can see from
   http://kegel.com/crosstool/current/buildlogs/
I've verified that the combinations
gcc-3.4.4 glibc-2.3.5 binutils-2.15 linux-2.6.8 (with gcc-3.4.4 as the core gcc)
gcc-3.4.4 glibc-2.3.2 binutils-2.15 linux-2.6.8 (with gcc-3.3.6 as the core gcc)
build toolchains that can build gdb and the 2.6 kernel,
so you're probably in luck.

Any reason you want to use gcc-3.4.0 instead of gcc-3.4.4?
There were some real bugs in gcc-3.4.0 that got fixed for 3.4.4.
