I think that sufficiet fix would be:

A scratch build with this patch succeeded, but I'm still puzzled why this fails on ppc32 only.

We pull in sd-daemon.c in anyway with libsystemd_daemon.la. So the patch should not be necessary. 

THis appears to be a problem with PPC only, maybe some toolchain issue?

I think ppc link is doing something right, its asking for resolving a symbol which it could not find in any library specified on cmdline but same thing on arm ld happily emits UND sd_notifyf and if you dump DT_NEEDED section then there is no asking for libsystemd-daemon.so so IMO non ppc architectures are doing it wrongly here.

on ppc

we dont have libsystemd-daemon.so.X there.

and sd_notifyf is referred from libsystemd_core_la-manager.o

When I compare cmdline for for linking .libs/test-unit-file on ppc and arm in both cases I see that we are asking for ./.libs/libsystemd-core.a libdbus-1.so -lpthread .libs/libudev.so -lrt -lcap libkmod.so -ldl

no where we are asking for linking with libsystemd_daemon which provides this symbol so I think systemd's link cmdline is incomplete here. It just happens to link on non-ppc architectures but if sd_notifyf() would be called by 'test-unit-file' at runtime by  it wont be resolved.

I have posted a patch for this here

http://lists.freedesktop.org/archives/systemd-devel/2013-January/008318.html

after this patch now DT_NEEDED looks good

and link also succeeds

Fixed in git.

This bug appears to have been reported against 'rawhide' during the Fedora 19 development cycle.
Changing version to '19'.

(As we did not run this process for some time, it could affect also pre-Fedora 19 development
cycle bugs. We are very sorry. It will help us with cleanup during Fedora 19 End Of Life. Thank you.)
