In my investigations for 'NULL fixup' (-> see
http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/89864/focus=89906)
pointed out that only symbols in 'absolute fixup' loop could be 'NULL'
if there is a not aliased/empty weakly linked symbol.
BTW: is such a situation normal? IIUC, it means there is a weakly linked 
symbol without *any* defintion, *and* it is referenced in the code. 
Granted, maybe it is checked before it is referenced, but we may want to 
check for and report at build time if possible. Would that be useful?
Amicalement,
