Make build_opt_tbl depend on config.h since it uses it.
Does it? As far as I know the tool does not use the values it checks at all. Thus, maybe, rather the check should be removed, than a dependency added
Error - Range end (122) does not match define (125) in line checksum 392 983 984
That error happens when CONFIG_LB_CKS_* change board to board and build_opt_tbl isn't rebuilt. Now I don't have get that error any more, but I'm open to other fixes.
You can check it by building the first VIA board, then building the Tyan s2895 with a make clean in the middle.
