rustc fails to build with object 0.35+

[klensy]

Building compiler with object updated to 0.35+ on x86_64-unknown-linux-gnu results with

  = note: rust-lld: error: /home/user/rust/build/x86_64-unknown-linux-gnu/stage1-std/x86_64-unknown-linux-gnu/release/deps/libpanic_unwind-0a0cf8f8a42e5845.rlib(lib.rmeta): SHT_STRTAB string table section [index 4] is empty
          collect2: error: ld returned 1 exit status

see rust-lang/rust#128040

I've bisected object to this #646 PR

https://rust-lang.zulipchat.com/#narrow/stream/182449-t-compiler.2Fhelp/topic/compiler.20fails.20to.20build.20with.20object.200.2E35

current master fd84037 fails too

Can you provide the object file that causes the error?

Thanks. Can you test if #710 works?
