Error while building: _FORTIFY_SOURCE requires compiling with optimization #27
Description
I'm trying to use melior, and I'm getting an error while building tblgen:

I'm using a version of llvm that I built from source with options:
cmake -G Ninja ../llvm -DLLVM_ENABLE_PROJECTS='mlir;clang' -DLLVM_BUILD_EXAMPLES=ON -DLLVM_TARGETS_TO_BUILD="Native" -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=ON -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++ -DLLVM_CCACHE_BUILD=ON -DLLVM_SOURCE_PREFIX=. -DCMAKE_INSTALL_PREFIX:PATH=/home/o/.local/software/llvm/versions/20.1.
I'm not sure if this is a bug with build.rs or if it's something I'm doing wrong.
