@madsmtm I am losing my mind that this was effectively the only problem. |

I don't know why that would be either. Maybe it's meant to be like "-g enables debuginfo", and "-g1 tweaks debuginfo, if it's enabled"?
Similar to how rustc's -Cdwarf-version doesn't have any effect without -Cdebuginfo.

Nit: Really should be:
Suggested change

| .flag("-gline-tables-only") |
For clarity.
(If that is supported by all tested compiler versions)

Tried that.
Breaks on half the platforms because that's a clang-only option and gcc doesn't support it, and cc will opportunistically find and use gcc instead.

Fixes #730 for good.
There was a subtle change in how appleclang interprets command lines between Xcode 16.2 and Xcode 16.4, which caused the cc-rs settings of first setting
debug(false)and then passing an explicit debuginfo setting to fail. This might have been inherited from upstream clang, and that is unclear to me. In any case it seems we can just pass-g1and that works fine.
