[flang][runtime] Build ISO_FORTRAN_ENV to export kind arrays as linka…
…ble symbols (llvm#95388) Moves definitions of the kind arrays into a Fortran MODULE to not only emit the MOD file, but also compile that MODULE file into an object file. This file is then linked into libFortranRuntime.so. Eventually this workaround PR shoud be redone and a proper runtime build should be setup that will then also compile Fortran MODULE files. Fixes llvm#89403 --------- Co-authored-by: Valentin Clement (バレンタイン クレメン) <[email protected]> Co-authored-by: Michael Kruse <[email protected]>
