Finally extracted one. Filed as:
    https://sourceware.org/bugzilla/show_bug.cgi?id=20796

It is triggered by a mix of -Wl,--gc-sections, -u buggy_symbol
and a shared library where 'buggy_symbol' comes from.

And while at it filed minor bug about R_68K_NONE relocations
to be present in final binaries:
