Linker in binutils 2.26 and newer generate GOT references instead PLT references when -z now is passed to linker. We need to extend scripts/localplt.awk to allow PLT or GOT references. [BZ #19007] * scripts/localplt.awk: Also allow GOT references. * sysdeps/unix/sysv/linux/i386/localplt.data: Mark _Unwind_Find_FDE, calloc, memalign, realloc and __libc_memalign with "+ REL R_386_GLOB_DAT". * sysdeps/x86_64/localplt.data: Mark calloc, memalign, realloc and __libc_memalign with "+ RELA R_X86_64_GLOB_DAT".
