Yes, and if you see under nand_spl/boar you have some examples how to
find additional files. You see that in Makefiles some local link are
created, and you could use the same mechanism to have a local asm-offsets.h

However, I agree that we should not generate broken link and IMHO the
position of asm-offsets.h is wrong. But again, the best thing should be
to generate this file automatically importing the mechanism from the kernel.

Best regards,
Stefano
