Cannot use customized LLVM by setting environ in the latest version

[seekamoon]

Hi,

I made some modifications on the SanitizeCoverage of LLVM and hope to use this customized LLVM when run bindgen. I can achieve this by setting the environLD_LIBRARY_PATH and LIBCLANG_PATH, making them point to llvm-project/build/lib. And this practice works well for the old version (0.69.4) of bindgen.

But for the latest version (0.72.0), I found that I cannot affect bindgen by setting LD_LIBRARY_PATH and LIBCLANG_PATH. It always tries to use the default LLVM libs.

I guess there should be something changed. Could someone tell me how to use a customized LLVM with the latest version?
