OK mate, trying installing headers from kernel linux-2.6.1 they seem to 
be better behaved with glibc-2.3.2. There are a few things you need to 
do for kernel versions 2.6.0 and above:

When installing kernel headers, instead of runnng "make symlinks" you 
need to run "make include/asm"

You need to setup a symbolic link "arch" in the kernel 
"include/asm-arm/" directory, which points to your chosen arm system type
eg. "cd include/asm-arm && ln -s arch-integrator arch && cd .." and then 
copy the kernel headers to your install directory. If you don't setup 
this symlink manually ("make include/asm" does not seem to do it) the 
compilation of glibc will fail:

----------------------------
Problem:
x86-cross-arm toolchain, binutils-2.14, gcc-3.3.2, glibc-2.3.2, linux-2.6.1
error including param.h when compiling glibc

Solution:
make a sysmlink "arch" to point to a directory of a particular arm 
system type in the "include/asm/" directory
e.g. "cd prefix/target/include/asm && ln -s ./arch-integrator arch"

In file included from 
/home/roman/crosstool/arm-unknown/arm-unknown-linux-gnu/include/linux/param.h:4,
                 from ../sysdeps/unix/sysv/linux/sys/param.h:24,
                 from ../sysdeps/unix/sysv/linux/init-first.c:26:
/home/roman/crosstool/arm-unknown/arm-unknown-linux-gnu/include/asm/param.h:13:45: 
asm/arch/param.h: No such file or directory
make[2]: ***

make[1]: *** [csu/subdir_lib] Error 2
make[1]: Leaving directory `/home/roman/crosstool/TOOLS/build/glibc-2.3.2'
make: *** [all] Error 2
----------------------------



After all the step above the compilation of glibc-2.3.2 still fails:

----------------------------
Problem:
x86-cross-arm toolchain, binutils-2.14, gcc-3.3.2, glibc-2.3.2, linux-2.6.1
error in a sed script when compiling glibc

Solution:
find a type in the sed script??

arm-unknown-linux-gnu-gcc    -shared 
-Wl,-dynamic-linker=/lib/ld-linux.so.2 -Wl,-z,combreloc \
  -x c /dev/null -o 
/home/roman/crosstool/TOOLS/build/glibc-build/format.lds.so 
-Wl,--verbose -v 2>&1 \
| sed -n -f scripts/output-format.sed > 
/home/roman/crosstool/TOOLS/build/glibc-build/format.lds.new
sed: file scripts/output-format.sed line 21: Unknown command: ``Q''
make[1]: *** [/home/roman/crosstool/TOOLS/build/glibc-build/format.lds] 
Error 1
make[1]: Leaving directory `/home/roman/crosstool/TOOLS/build/glibc-2.3.2'
make: *** [install] Error 2
----------------------------

so as you can see there are loads of bugs/problems, you could try the 
latest CVS version of glibc, or try fixing the apprently broken sed 
script in glibc-2.3.2/scripts/output-format.sed
