Application driven by the sniperkill script.

signal(7) states that signal # 31 for ppc, *86, etc should result in
termination only, in the 3rd column, but the `will be SIGSYS' comment is
unnecessarily ambiguous:

       SIGUNUSED    -,31,-     Term    Unused signal (will be SIGSYS)

       SIGSYS      12,-,12     Core    Bad argument to routine (SVID)

The behavior as shown in my log for the `sniperkill' test I've recommended
adding to LTP demonstrates that the behavior for SIGUNUSED matches SIGSYS.

The documentation for SIGUNUSED should either clearly state a) that the process
will `Core'-dump, and/or the indirection should be changed such that SIGUNUSED
directly maps to SIGSYS.

I've attached the logs and test. The email to ltp-list is in the URL field.
