The reason is that for such arch values '.arm' directive and arm opcodes are not allowed. Fix conditionally enables arm opcodes only if no CONFIG_CPU_THUMBONLY defined and it uses .org instructions to keep sigreturn_codes layout.

Move sigreturn_codes to separate .S file and use proper assembler mnemonics for these code snippets. In this case compiler will take care of proper instructions byteswaps for BE8 case. Change assumes that sufficiently Thumb-capable tools are used to build kernel. Problem was discovered during ltp testing of BE system: all rt_sig* tests failed. Tested against the same tests in both BE and LE modes.
