• Reintroduces the output of undefined symbols as dynamic symbols, which may have been intentionally removed in a previous commit (9e10fcf71c11).
• Fixes a regression that caused crashes or errors when linking with ``--unresolved-symbols=ignore-in-object-file``.

[PATCH] RISC-V: Also output undefined symbols as dynamic symbols

The patch addresses an issue in the RISC-V linker where undefined symbols were not being correctly output as dynamic symbols when the --unresolved-symbols=ignore-in-object-file option was used. This would lead to either a crash when linking with -no-pie or an error message when linking with -pie. The fix involves re-introducing the output of undefined symbols as dynamic symbols, which was removed by commit 9e10fcf71c11. This ensures that these symbols can be resolved by the dynamic linker at runtime.
