linker script symbol reference

[Constantine Kousoulos]

I think i have found out what's the problem.

Pointer types in 64-bits are always 8 bytes whereas pointer types in 
32-bits are 4 bytes.

Although symbols in linker scripts are represented by integers (4 bytes) 
in C, their addresses must be 8 bytes in a 64-bit system. So, by 
defining vm_offset_t to be unsigned long or long, the problem ceases to 
exist.

It seems that it was not a binutils problem after all. Sorry! :)

Please don't hesitate to provide more input on the subject if you find 
any errors in my thoughts.
