Thanks @tarunprabhu for providing the instructions.

I am currently hitting the following error. Is the `lit.local.cfg` a generated file? Or is it missed in this patch?

  CMake Error at Fortran/gfortran/regression/CMakeLists.txt:1839 (file):
    file COPY cannot find
    "/home/kircha02/llvm-test-suite/Fortran/gfortran/regression/lit.local.cfg":
    No such file or directory.

I am trying to run this on AArch64 by commenting out the check for `X86`.
