I just tried this patch but it seems to fail when it tries to build a shared libFortran_main.so:

  [31/34] Linking C shared library lib/libFortran_main.so.15git

This is the cmake I am using:

  cmake ../llvm -G 'Ninja' \
        -DCMAKE_INSTALL_PREFIX=$TOP/install/ \
        -DCMAKE_BUILD_TYPE=Release \
        -DLLVM_ENABLE_ASSERTIONS=ON \
        -DLLVM_ENABLE_PROJECTS="clang;mlir;openmp;flang" \
        -DLLVM_TARGETS_TO_BUILD="X86;AMDGPU" \
        -DBUILD_SHARED_LIBS=ON \
        -DLLVM_INSTALL_UTILS=On \
        -DCMAKE_CXX_STANDARD=17
