sco5.h: Let ELF use dwarf2 unwinding.
* i386/sco5.h: Let ELF use dwarf2 unwinding. COFF uses sjlj.
(EH_FRAME_SECTION_ASM_OP, EH_FRAME_SECTION_ASM_OP_ELF): Defined.
(EH_FRAME_SECTION_ASM_OP_COFF): Likewise.
(DWARF2_UNWIND_INFO): Let this track object file format.
(EXTRA_SECTIONS): Add in_eh.
(EH_FRAME_SECTION_ASM_OP, EH_FRAME_SECTION_ASM_OP_ELF): Define.
(EH_FRAME_SECTION_ASM_OP_COFF): Likewise.
