Move eelf_mipsel_haiki.c to ALL_64_EMULATION_SOURCES

Move eelf_mipsel_haiki.c to ALL_64_EMULATION_SOURCES

--enable-targets=all on a 32-bit host results in a link failure with
undefined references due to elfxx-mips.c not being compiled.  This
patch fixes that by putting eelf_mipsel_haiki.c in the correct
EMULATION_SOURCES Makefile variable.  I've also added a bunch of
missing file dependencies and sorted a few things so that it's easier
to verify dependencies are present.

	* Makfile.am: Add missing haiku dependencies, sort.
	(ALL_EMULATION_SOURCES): Sort.  Move eelf_mipsel_haiku.c to..
	(ALL_64_EMULATION_SOURCES): ..here.  Sort.
	* Makfile.in: Regenerate.
