I used srpm from fedora 20 build and _hardened_build was available in spec
file. I expected all builds(f19, f20, rawhide} use the same spec file.

There is condition in spec file
%if (0%{?fedora} > 15 || 0%{?rhel} >= 7)
%define _hardened_build 1
%endif

So _hardened_build will not be defined on other platforms (e.g. opensuse)
and there will be the same problem with linking ipa-otpd

Other option is to remove "duplicated" hardened flags from AM_LDFLAGS

-AM_LDFLAGS := $(LDFLAGS) @LDAP_LIBS@ @LIBVERTO_LIBS@ @KRAD_LIBS@ -pie 
-Wl,-z,relro -Wl,-z,now
+AM_LDFLAGS := $(LDFLAGS) @LDAP_LIBS@ @LIBVERTO_LIBS@ @KRAD_LIBS@
