x86: Correct unwind information for the second PLT 

For i386, generate unwind information for the second PLT.  For x32,
correct alignment of .eh_frame section for the second PLT.

bfd/

	PR ld/22061
	* elf32-i386.c (elf_i386_link_setup_gnu_properties): Create
	.eh_frame section for the second PLT.
	* elf64-x86-64.c (elf_x86_64_link_setup_gnu_properties): Correct
	alignment of .eh_frame section for the second PLT.
