slapd daemon hits segmentation fault during start while running openldap test.
patch openldap-security-pie.patch was causing segmentation fault in s390x architecture. S390x arch requires -fPIE option instead of -pie .
From man page of gcc it is specified as follow:
-pie options assumes GOT entries and small data are within a 12-bit range from the
GOT base address; with -fPIC or -fPIE, GOT offsets are computed with 32 bits.
The -pie option was causing segmentation fault in s390x.
Attached patch fixes the issue.

while having a look ...
-f option in the link phase seems to be different and hence i think it doesnt make it Position independent.
i have misunderstood the option of gcc with ld...However the following patch openldap-security-pie.patch is causing problem...Will try to fix it..

One way to overcome this might be to export CFLAGS="-fPIC" in the openldap.spec if it is s390x....
Pushed (to master only):
You can find a srpm at http://koji.fedoraproject.org/koji/buildinfo?buildID=472772.
I tested this on an s390x machine and all seems fine. I'll leave this in master for a while, unless I have a positive response from the reporter.
