[flang-commits] [flang] [Flang][test] Account for FLANG_TEST_Fortran_FLAGS (PR #213964)

[Michael Kruse via flang-commits]

https://github.com/Meinersbur created https://github.com/llvm/llvm-project/pull/213964

FLANG_TEST_Fortran_FLAGS allows adding additional flags when running Flang's test. It is typically used for standalone builds of Flang where the intrinsic modules are not (and cannot be) built using LLVM_ENABLE_RUNTIMES=flang-rt.
