I believe this causes:

/home/bmg/build/glibcs/s390-linux-gnu/glibc/login/utmpdump.o: In
function `main':
/home/bmg/build/glibcs/s390-linux-gnu/glibc-src/login/programs/utmpdump.c:93:
undefined reference to `getutent'
collect2: error: ld returned 1 exit status

That's presumably due to the renaming business in
sysdeps/unix/sysv/linux/s390/s390-32/getutent*.c

Thanks,
Florian
