	* binutils-all/readelf.exp: Don't regard mips*el-*-* as traditional
	mips.
	* gas/mips/mips.exp: Likewise. Use traditional testcases for
	mips${el}16-f if needed.
	* gas/mips/elempic.d: New file, testcase for little endian empic.
	* gas/mips/elfel-rel2.d: Don't test trailing zeroes in dump.
	* gas/mips/mips16-f.d: Use non-traditional symbol sorting.
	* gas/mips/mipsel16-f.d: Likewise.
	* gas/mips/mipsel16-e.d: New file, testcase for little endian MIPS16
	relocations.
	* gas/mips/tmipsel16-f.d: New file, testcase for little endian MIPS16
	relocations, traditional variant.
