* emultempl/mmo.em (mmo_place_orphan): Rewrite to also attach

	orphan sections to .data and .bss output sections, not just .text.
	When giving up on finding a suitable output section, attach to any
	output section other than .MMIX.reg_contents, if it exists.
	* scripttempl/mmo.sc: Move output debug sections to just before
	.MMIX.reg_contents.  Add .gnu.attributes.  Add new . = . NOP
	assignments and move end-of-section provide-symbols after them
	to force the end-of-section symbols to the address after orphan
	placement.  Add SORT_NONE to .init and .fini sections.
