Actually, no.  That won't help.

Shared object libraries are not created with  'ar',  rather  with
'ld'.   The closest that I can think of to documentation would be
to read 'man ld' and  look  for a  description  of '-Bshareable'.
It  is   possible   that   this   documentation   is   not   100%
accurate   due   to   FreeBSD   specific  differences  in  object
structures.  I really cannot speak authoritatively on this.
