The test exercises a regression of extra `-Zbuild-std-features` overriding the entire default-features set. However, after rust-lang/rust 146317 panic_immediate_abort became a codegen flag not a Cargo feature anymore. We pick another `optimize_for_size` feature flag to ensure the regression case is still covered. To verify `optimize_for_size` actually triggers the regression, git revert f004691 and changes to `-Zbuild-std-features=optimize_for_size`. Alternatively, we can just drop this test.

What does this PR try to resolve?
The test exercises a regression of extra
-Zbuild-std-featuresoverriding the entire default-features set.
However, after rust-lang/rust#146317 panic_immediate_abort
became a codegen flag not a Cargo feature anymore.
We pick another
optimize_for_sizefeature flag to ensure theregression case is still covered.
How to test and review this PR?
To verify
optimize_for_sizeactually triggers the regression,git revert f004691
and changes to
-Zbuild-std-features=optimize_for_size.Alternatively, we can just drop this test.
