x86-64: Rename .plt.bnd to .plt.sec
Rename .plt.bnd to .plt.sec to indicate that this is used as the second PLT section. There is no change in run-time behavior. We also scan the .plt.sec section to synthesize PLT symbols. bfd/ * elf64-x86-64.c (elf_x86_64_link_hash_entry): Rename plt_bnd to plt_second. (elf_x86_64_link_hash_table): Rename plt_bnd/plt_bnd_eh_frame to plt_second/plt_second_eh_frame. (elf_x86_64_link_hash_newfunc): Updated. (elf_x86_64_allocate_dynrelocs): Likewise.

Create the .plt.sec section instead of the .plt.sec section. ld/ * emulparams/elf_x86_64.sh (TINY_READONLY_SECTION): Replace .plt.bnd with .plt.sec. * testsuite/ld-x86-64/bnd-ifunc-1-now.d: Likewise. * testsuite/ld-x86-64/bnd-ifunc-2-now.d: Likewise. * testsuite/ld-x86-64/bnd-ifunc-2.d: Likewise. * testsuite/ld-x86-64/bnd-plt-1-now.d: Likewise. * testsuite/ld-x86-64/bnd-plt-1.d: Likewise. * testsuite/ld-x86-64/mpx3.dd: Likewise. * testsuite/ld-x86-64/mpx3n.dd: Likewise. * testsuite/ld-x86-64/mpx4.dd: Likewise. * testsuite/ld-x86-64/mpx4n.dd: Likewise. * testsuite/ld-x86-64/plt-main-bnd-now.rd: Likewise. * testsuite/ld-x86-64/pr21038b-now.d: Likewise. * testsuite/ld-x86-64/pr21038b.d: Likewise. * testsuite/ld-x86-64/pr21038c-now.d: Likewise. * testsuite/ld-x86-64/pr21038c.d: Likewise.
