[binutils-gdb/binutils-2_28-branch] Don't use elf_i386_eh_frame_plt directly


https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=cd3ffd4ed23eeb517f28c7c761e1f2def6268ca2

commit cd3ffd4ed23eeb517f28c7c761e1f2def6268ca2
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Tue Jan 10 11:30:25 2017 -0800

    Don't use elf_i386_eh_frame_plt directly
    
    Use eh_frame_plt_size and eh_frame_plt from elf_i386_plt_layout for
    .eh_frame covering the .plt section.
    
    	Backport from master
    	* elf32-i386.c (elf_i386_size_dynamic_sections): Set
    	plt_eh_frame->size to eh_frame_plt_size and use eh_frame_plt.
