Subject: [PATCH] ld: Add OTHER_PLT_SECTIONS

OTHER_PLT_SECTIONS contains sections which should be placed right after
.plt section.

	* emulparams/elf32_x86_64.sh (TINY_READONLY_SECTION): Renamed
	to ...
	(OTHER_PLT_SECTIONS): This.
	* emulparams/elf_i386.sh: Likewise.
	* emulparams/elf_iamcu.sh: Likewise.
	* emulparams/elf_x86_64.sh: Likewise.
	* scripttempl/elf.sc: Place ${OTHER_PLT_SECTIONS} just after
	.plt.
