 * LL_DELAY_LOAD means  (if on) that  rld will not load the DSO
 * refered to by the liblist entry till something in the DSO

 *
 * LL_EXPORTS is ignored by rld. It informs that ld exported symbols 
 * from the liblist-entry DSO into the main DSO (that this
 * liblist entry is part of).
 *
 * LL_IGNORE_INT_VER means (if on) that all version checks
 * should be suppressed and the DSO accepted based on
