spurious obsolete markings for shlibs

[Greg Troxel <gdt%ir.bbn.com@localhost>]

In src/distrib/sets/lists/base/shl.elf on netbsd-4, several libraries
are listed as obsolete, but this removes the only major version of a
library, breaking old binaries.  The following diff would pull up parts
of the changes from 1.135-1.140 along the head.  Does anyone object to
me submitting a pullup request for netbsd-4?
