FAIL:
glibc-2.12-1.7.el6.s390
prelink-0.4.3-4.el6.s390x
gcc-4.4.4-13.el6.s390x

PASS:

gcc-4.1.2-46.el5_4.2.s390x
kernel-2.6.18-164.25.1.el5.s390x

It crashes on:
./sysdeps/s390/s390-32/elf/start.S
.L21:   l       %r5,36(%r9)    /* Load the e_flags field.  */
$r3 = in-file address
$r9 = (in-memory - in-file) offset
$r11 = in-memory address

Prelinking PIE does not make much sense but it can be run everywhere else.

It affects GDB gdb.base/break-interp.exp testcase.
