Little-endian or1k in binutils is unavailable or severely broken.

[ilyakurdyukov]

In some files I found that theoretically binutils supports little-endian OpenRISC, but I can't get the assembler to compile in little-endian format, there's simply no such option for or1k!

I can ask objdump to disassemble in little-endian format, but then half the instructions are broken:

objdump -D -b binary -EB -m or1k test_be.bin

   0:	18 60 07 27 	l.movhi r3,0x727
   4:	a8 63 0e 00 	l.ori r3,r3,0xe00
   8:	9c 63 ff ff 	l.addi r3,r3,-1
   c:	bc 43 00 00 	l.sfgtui r3,0
  10:	13 ff ff fe 	l.bf 0x8
  14:	44 00 48 00 	l.jr r9

objdump -D -b binary -EL -m or1k test_le.bin

   0:	27 07 60 18 	*unknown*
