libclc build fails when compile with CUDA and using Make

[sarnex]

Describe the bug

Really weird issue, the build failure only occurs with make, it works fine with ninja.

To reproduce

Make sure you have a supported CUDA SDK installed

git clone https://github.com/intel/llvm
cd llvm
python buildbot/configure.py -G"Unix Makefiles" --cuda
python buildbot/compile.py

[ 94%] Generating ../../lib/clc/libspirv-nvptx64--nvidiacl.bc
No such file or directory

and if you check the verbose logs

cd build
make deploy-sycl-toolchain VERBOSE=1

[ 94%] Generating ../../lib/clc/nvptx64--nvidiacl.bc
cd /tmp/llvm/build/tools/libclc && ../../bin/prepare_builtins -o /tmp/llvm/build/./lib/clc/nvptx64--nvidiacl.bc /tmp/llvm/build/tools/libclc/obj.libclc.dir/nvptx64--nvidiacl/builtins.opt.nvptx64--nvidiacl.bc

and if we use ninja instead

python buildbot/configure.py  -G"Ninja" --cuda
python buildbot/compile.py

and it will pass

Environment

Linux Ubuntu 24.04 with CUDA SDK installed

FYI @wenju-he

[wenju-he]

thanks @sarnex for reporting. It is because output directory is not created and then libclc library files can't be saved to output directory. Will be fixed by #20063

[sarnex]

Thanks so much for the quick fix!
