GNU ar did NOT implment option -q as a synonym of -r as the manual

GNU ar did NOT implment option -q as a synonym of -r as the manual
page stated, thus BSD ar(1) option -q, which was implemented based on
the GNU ar manual page, turns out to be incompatible with GNU ar -q.

This change will make BSD ar(1) -q a *REAL* GNU ar -q:

1. It will update symbol table. (same as unfixed version)
2. It will NOT compare new members spcified in the command line args
   with existing members, instead, append them directly.
