Having a good automatic way to minimize the bootblock size is very 
useful. As for backwards compatibility, what do you mean - updates? The 
bootblock complicates any attempt to do safe updates currently. This 
change won't improve it, but it won't make it worse.

Should be fine.

My only issue is that I don't know if its behaviour is stable. ld 
prefers to work from bottom to top in the address space and this 
solution might interfere.
How can we get an "official" statement if this method is supported or 
just luck that it works right now? A mail to the binutils list?
