For some reason a pure GCC build on my 10.6 did not complain, but Clang + gfortran on CI fails: https://github.com/macports/macports-ports/actions/runs/9487009099/job/26142622690?pr=24455

UPD. That is because on 10.6 with gcc it detected no LTO support, so it was disabled, and offending flag was not added.

Thank you for raising this, @barracuda156. I reproduced the issue on my mac, addressed in https://github.com/ERGO-Code/HiGHS/pull/1802, which will be merged in latest after @jajhall 's review.
