commit 7235427998571b6d8267e7ac72a52d7b082f4c2b

    dwarf2: Use octets for dwarf2 headers
    
    The content of the dwarf2 sections .debug_line, .debug_aranges and
    .debug_info starts with an u32 containing the the size of the remaining
    data.  According to the dwarf2 specification this value must be expressed
    in octets instead of bytes.
    
    	* dwarf2dbg.c (out_debug_line): Use octets for dwarf2 headers.
    	(out_debug_aranges, out_debug_info): Likewise.
