Fix compilations for parisc
pagebuf_lock_value dereferences struct semaphore, but the layout of             
it is machine-dependent.  Most architectures use a layout were                  
the dereference in pagebuf_lock_value is fine, but for example                  
parisc doesn't.                                                                 
                                                                                
pagebuf_lock_value isn't ever called in non-debug builds so compile             
it only for debug builds
