Add CONFIG_SYS_SYM_OFFSETS to support offset symbols
Link symbols as created by the link script can either be absolute or

so that we can support both.
As we convert architectures over to generic board, we can see if this
option is actually needed, or whether it is possible to unify this feature
also.
