[PATCH] D145389: [lld][flang] Add exceptions for Flang runtime libraries on MinGW.

[Markus Mützel via Phabricator via llvm-commits]

mmuetzel added a comment.

The command from the downstream example expands to the following for me:

  $ flang -### test-cdotu.f -otest-cdotu -lblas

Different to the `libclang_rt.builtins-x86_64` archive, the Fortran library is linked via `-l` flags (not via the full path to the library).

Does it need to be treated differently?
