i thought the fix was self-evident ;)

you cant just use straight symbol names in common header files as they
dont take into consideration weird arch-specific ABI conventions.  in
the case of Blackfin/h8300, the ABI dictates that any C-visible
symbols have an underscore prefixed to them.  thus all symbols in
vmlinux.lds.h need to be wrapped in VMLINUX_SYMBOL() so that each arch
can put hide this magic in their own files.
