Absolute symbol should contain its absolute value, but LLD had been writing its RVA instead. Write its VA instead. DefinedSynthetic were being skipped before with the reasoning "Relative symbols are unrepresentable in a COFF symbol table", which is only true if the RVA points to outside of a section. LLD does create synthetic symbols which points to actual data chunks (typical for symbols embedded into the load config directory). Write these symbols to the COFF symbol table too.
