My product currently uses a 2.4 kernel and I have been trying to
update the tools to try and get a slight increase in performance.

This is good to hear maybe I can get my manager to skip doing this project :)

I used ftp://ftp.denx.de/pub/eldk/4.2/arm-linux-x86/sources/SRPMS/crosstool-0.43-3.src.rpm

I will try and ensure I use $ <ELDK_root>/usr/bin/rpmbuild

There are errors from mawk when it is trying to run
/opt/arm-eldk/usr/src/denx/BUILD/crosstool-0.43/build/gcc-4.2.2-glibc-20070515T2025-eldk/arm-linux-gnueabi/glibc-20070515T2025/scripts/gen-sorted.awk

It appears that
/opt/arm-eldk/usr/src/denx/BUILD/crosstool-0.43/build/gcc-4.2.2-glibc-20070515T2025-eldk/arm-linux-gnueabi/glibc-20070515T2025/scripts/lib-names.awk
is supposed to create the lib-names.h file but the log doesn't show
mawk being run on this file.  I have been unable to find the code that
is trying to run mawk on lib-names.awk in order to determine why it
isn't being run.

Please let me know if you have any other suggestions.

Thanks,
Gabe
