Test #119: x86_64-gdb-index-dwarf5 fails

[ms178]

With c7129916eeb6df2b57d88415a16a28c09ec01b1a and the CachyOS distro compiler (GCC 13.2.1 20230801), I see a test failure that I didn't get before on an earlier recent mold-git revision (0eea8f401509b882d41264990b53cdf75416f515):

Can reproduce locally CI is also failing: https://github.com/rui314/mold/actions/runs/6391489275/job/17346876069

[rui314]

I can confirm the issue. It is extremely odd that that change caused this error, but for now, I'll revert it to fix CI.
