Current we drop the insertion of a whole symbol table if the name
of one symbol already exists in the base table. Having similar
symbols across different binaries is very common.
This change adds a warning and recommends a fix instead of silently
dropping the table. This is useful for debugging when there are two
or more workloads, e.g. bootloader + kernel, are added separately.
