Contributes to #6264.

After merging #6265, I thought more about this comment from @fabsig : #6265 (comment).

I think it's possible that differences in compiler flags could lead to different behavior and maybe a false negative on the CI jobs intended to reproduce the CRAN check.

CRAN's flags for the clang18 check are described here:

I noticed some of those flags weren't showing up in logs. This adds them to get closer to CRAN's configuration and therefore improve our confidence that these CI checks passing means a new submission to CRAN will pass.
