    rtld: Add write-lock to case of filter loading
    
    Propagate the current state of rtld_bind_lock to dlopen_object() calls
    through the filter loading call chain. This fixes attempts to
    write-lock the already locked rtld_bind_lock when filter loading is
    initiated by relocation of dlopening dso.
    
    Taken from: FreeBSD SVN 234170 (12 APR 2012)
    
    Do not try to adjust stacks if dlopen_object is called too early.  This
    is a follow-up to FreeBSD SVN 233231 which fixed a similar issue with
    object initialization code.
