Alan Modra c2e863866d ld -r script fixes
For ld -r, we generally set the VMA of sections to zero.  This is done
to make the output of ld -r most similar to that output by the
assembler, which generally has sections starting at VMA zero.  In some
cases that covers for backend bugs which would mis-handle relocatable
object files with non-zero section VMAs.

This patch fixes a few sections that didn't have zero VMAs for ld -r.
A missing zero on .note.gnu.build-id and .eh_frame_hdr doesn't matter
much since these are linker generated symbols only output on final
link, but it's good to be consistent.

	* Makefile.am (ei386beos.c, ei386go32.c): Correct dependencies.
	* Makefile.in: Regenerate.
	* scripttempl/elf.sc (.note.gnu.build-id, .eh_frame_hdr): Set
	address with ${RELOCATING-0}.
	* scripttempl/arclinux.sc: Likewise.
	* scripttempl/armbpabi.sc: Likewise.
	* scripttempl/avr.sc: Likewise.
	* scripttempl/elf64hppa.sc: Likewise.

	* scripttempl/elfxtensa.sc: Likewise.
	* scripttempl/mep.sc: Likewise.
	* scripttempl/nds32elf.sc: Likewise.
	* scripttempl/pru.sc: Likewise.
	* scripttempl/elf32msp430.sc: Likewise, and for other sections.
	* scripttempl/epiphany_4x4.sc: Similarly.
