ld.lld: error: undefined symbol: main

Seems it auto-detects ld.lld and attempts to use it, works fine if it's not installed.

[Comment 2 Will Lepofsky 2021-10-07 03:43:14 UTC]

Problem still exists for 4.4.4, 4.4.8, and 5.0.2.

[Comment 3 Will Lepofsky 2022-03-08 23:58:36 UTC]

Problem still exists with version 5.0.5 as well.

Please try the attached patch. Usually there isn't a need to keep listing affected versions though. Attaching a patch is the best way to get something moving if it seems stalled.

If I knew what to patch, I would have submitted the bug with a patch.  Thanks for the patch you provided, I'll try your patch over the weekend.
