Looks like this was caused by #95612 (cc @davidtwco). It looks like that also caused issues with openbsd (#96597), I'm wondering if it would make sense to audit which platforms were affected to make sure they are all addressed?
Passing
-Zunstable-optionsseems like a somewhat blunt solution. I would expect it to not pass-Csplit-debuginfoif the target does not support it and the user did not specify it. That is roughly what Cargo does, though I suspect that might be not as easy to do in bootstrap.davidtwco commentedon Jul 13, 2022
I'm not sure there's a great way of solving this properly in bootstrap. It should be solved for good by #98051 but if you want to submit a PR in the meantime that adds a condition for Solaris then I can r+ it.
