patch for SVR5-based systems.



This cleans up a wierdness when linking a native object was built with
-g with EGCS.   It also activates DWARF-2 debugging for these two targets.


* i386/sysv5.h: New file to describe UnixWare7/SVR5.
* configure.in (i?86-UnixWare7*-sysv): Use it.
* i386/udk.h: Use sysv5.h.   Activate Dwarf-2.
