IMO the SysV AMD64 psABI blesses .eh_frame as something that programs can
rely on for unwind info, while .debug_frame is only covered by DWARF. The
way I see it, the ABI takes precedence over the previous way of storing
unwind info. On the other hand if Go never wants to coexist with any other
exception-using or stack crawling code, then maybe omitting it makes sense.
