[sp] I did the same - but focused only on .rel.dyn and .bss

[sp] I am trying on this. Getting back to linker scripts after many
years. But assuming that there is no way; I am still looking
for an explanation on:
1) why the current metod produces different errors across
different toolchain versions.
2) How does presence of one variable alone breaks the build?
At least, compiler doesn't complain. Even moving it out
of .bss by explicit initialization doesn't help.
BTW, I verified that it is not used anywhere till end of
board_init_f() - didn't go further. Should I?
Can yo help me on these?
