This was added in commit 98d0f918ba (LFortran: Add support for this
compiler, 2024-01-25, v3.31.0-rc1~303^2~2) because it is needed for
cases covered by CMake's Fortran tests. However, it does not work
with Fortran modules and breaks lfortran's own `examples/project1`.
Move the flag to the test cases that need it, just as the original
commit did with `--implicit-interface`.
Fixes: #26597
