H.J. Lu f2c29a1692 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.

	* 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_get_synthetic_symtab): Updated.  Also scan the
	.plt.sec section.
	(elf_backend_setup_gnu_properties): Updated.  Create the
	.plt.sec section instead of the .plt.sec section.
