CI Linux x64 failure on llvm-profdata: command not found

[Evanyl]

In the Linux x64 CI test for #144176, the Flang.Profile/gcc-flag-compatibility.f90 test fails with

+ llvm-profdata merge /home/gha/actions-runner/_work/llvm-project/llvm-project/flang/test/Profile/Inputs/gcc-flag-compatibility_IR.proftext -o /home/gha/actions-runner/_work/llvm-project/llvm-project/build/tools/flang/test/Profile/Output/gcc-flag-compatibility.f90.tmp.dir/some/path/file.prof
/home/gha/actions-runner/_work/llvm-project/llvm-project/build/tools/flang/test/Profile/Output/gcc-flag-compatibility.f90.script: line 4: llvm-profdata: command not found

which seems unrelated to this PR.

I have encountered this failure on both Windows and Linux. It seems to be caused by a test added here: #142892.
