Mhh sorry, I work only on UNIXish systems and I tend to forgot about other 
systems. Hovewer since bl offset precision is a half-word, at least on arm I'm 
sur a GOT entry for a function can't be less than half-word aligned. Since the 
first patch only set the lowest bit in case of a GOT entry for a function, 
that is fine.

I'll thus revert to the first version.

Thanks for your input
