[flang] Fix Preprocessing/bug129131.F test on Darwin (#123094)

luporl · web-flow · commit 9ed075595e14 · 2025-01-16T10:21:21.000-03:00
On Darwin, the --isysroot flag must also be specified. This
happens when either %flang or %flang_fc1 is expanded. As -fc1 must
be the first argument, %flang_fc1 must be used in tests, instead of
%flang -fc1.
