systemd build failure on ppc64 archi about hidden symbol not defined locally

as per OBS current status (1) the systemd failed to build
I tried removing the last three patches but still have same reported error.

On systemd irc there were a suggestion that could be related to lto,
but the current gcc version do not handle --disable-lto option.

Do somebody has a suggestion for me to continue the investigation ?
