Sorry for that. This is caused by lto-cgraph using the set_decl_init_priority 
that
it should not.  I am sure I updated this once already.  This patch fixes the 
problem.

Bootstrapped/regtested x86_64-linux, comitted.

        * lto-cgraph.c (lto_output_node, input_node): Set/get init/fini priority
        directly.
