gdb 4.7 doesn't compile on a Sun 3 running 3.5 configured as sun3os3.

There were two small configuration problems: in the glob and readline
directorys, sysdep.h was linked to sysdep-norm.h instead of
sysdep-obsd.h.

After fixing that, all the libraries compiled.  But gdb/sun3-nat.c
didn't compile, because it used a type `struct fpu' which isn't declared
in Sun Unix 3.5's header files.  There seemed to be some similar types,
but nothing exactly analogous.

I couldn't understand what gdb needed in the type, so unfortunately I
can't give a patch, which, I realize probably means nothing can be
done, as I feel like I'm the only person left using 3.5 (a vast
improvement over 4.x, in my opinion, but that's a different article :-)).
