With e.g. v2.6.21 it's even worse. I get for each build:
...

The result is the same for v2.6.22 and v2.6.23.
Bisecting this yielded 0b35786d77ba4037f181982cc8ca20a7a3bf0fd2.
The script used for building is:
#! /bin/bash -e
seq -w 1 100 | while read i; do
echo "********************* run $i *************************";
rm -rf ../obj;
mkdir ../obj;
delmake O=../obj ns9xxx_defconfig;
if ! delmake O=../obj -j 3 uImage zImage Image; then
break;
fi;
done;
