  Log Message:
  -----------
  [yaml2obj] - Improve handling of the SHT_GROUP section.

Currently, when we do not specify "Info" field in a YAML description
for SHT_GROUP section, yaml2obj reports an error:
"error: unknown symbol referenced: '' by YAML section '.group1'"

Also, we do not link it with a symbol table by default,
though it is what we do for AddrsigSection, HashSection, RelocationSection.

The patch fixes missings mentioned.
