(ppc_build_one_stub): Likewise. (ppc64_elf_build_stubs): Likewise for glink. ld/testsuite/ * ld-powerpc/tls.s: Add proper .opd entry for _start. * ld-powerpc/tlstoc.s: Likewise. * ld-powerpc/relbrlt.d: Update for changed stubs. * ld-powerpc/tls.d: Update for changed stubs and _start .opd entry. * ld-powerpc/tls.g: Likewise. * ld-powerpc/tlsexe.d: Likewise. * ld-powerpc/tlsexe.g: Likewise. * ld-powerpc/tlsexe.r: Likewise. * ld-powerpc/tlsexetoc.d: Likewise. * ld-powerpc/tlsexetoc.g: Likewise. * ld-powerpc/tlsexetoc.r: Likewise. * ld-powerpc/tlsso.d: Likewise. * ld-powerpc/tlsso.g: Likewise. * ld-powerpc/tlsso.r: Likewise. * ld-powerpc/tlstoc.d: Likewise. * ld-powerpc/tlstoc.g: Likewise. * ld-powerpc/tlstocso.d: Likewise. * ld-powerpc/tlstocso.g: Likewise. * ld-powerpc/tlstocso.r: Likewise.
