2.6.13-rc3 test: finding compile errors with make randconfig

[Grant Coady <lkml@dodo.com.au>]

Greetings,

Few days ago I compiled 241 random configurations of 2.6.13-rc3, today 
I finally got around to parsing the results, top 40, sorted by name.  
Percentage is error_builds / total_builds.

build script similar to:
count=0
while [ $((++count)) -le $limit ]; do
        trial=$(printf %003d $count)
        make randconfig
        cp .config "$store/$trial-config"
        make clean
        make -j2 2> "$store/$trial-error"
done

Curious whether this is worth doing, I'm about to start a run for 2.6.12.3, 
any interesting errors I can find the particular config + error to recover 
context.  Deliberately simplistic for traceability at the moment, truncated 
error length for this post.
