svn commit: r335897 - head/lib/libc

Log:
  Strip __RCSID() and __SCCSID() strings by default when building libc.
  
  This is in preparation for changes to update the various ID strings in
  libc's source.  CSRG ID strings will use __SCCSID() and there are some
  existing uses of __RCSID() for NetBSD ID strings already.  These are
  generally under either an explicit #if 0 or an #ifdef LIBC_SCCS so are
  off by default and this change preserves that existing behavior.
