Yes, I think the root cause is what you mentioned - RISC-V GNU ld doesn't
support the TLS transitions. I have taken a loot at this, we can refer to what
x86 did in the elf_i386_tls_transition, and then remove the unused GOT/PLT
relocations in the elf_i386_relocate_section, by handling "wrel".
This is RISC-V's TODO for many years, but seems like an optimization, so I
think the priority isn't very high for now. If someone is interested in this
issue, the above information should be helpful.
