After some searching we found that this is caused
by some conflict between using gcc 3.3 and the
sles8-s390 2.4.19 kernel. By default sles8-s390
comes with gcc 3.2 which works fine.
Here are the combinations I have tried:
gcc 3.2 gcc 3.3
------- -------
kernel 2.4.19 works fails
kernel 2.4.21 works works
The sles8-s390 Service Pack 3 ships the 2.4.21 kernel level,
so applying that service pack is one solution to the problem.
Using gcc 3.2 for any kernel related (including LiS) compiles
is another solution.
A 'hack' is to copy the /usr/src/linux*/include/asm-s390/unistd.h
from a 2.4.21 kernel to the 2.4.19 system to do the LiS build.
The gcc 3.3 level is shown as recommended for the
June 2003 stream at the IBM developerworks web site:
http://www10.software.ibm.com/developerworks/opensource/linux390/june2003_recommended.shtml
but only if you also go to the recommended 2.4.21 kernel.
