2013-04-15Check regular reference without non-GOT referenceH.J. Lu2-14/+18
non_got_ref may not be set when building shared library. We need to set non_got_ref if there are any non-PIC relocations. But we only did this when there were no PLT/GOT relocations. It failed when there is a PLT relocation. This checkin moves the non_got_ref check out. bfd/ 2013-04-15 H.J.
