# bindgen uses the clang-sys crate to locate a 'clang' executable for querying
# default include paths. clang-sys's search order is: CLANG_PATH, libclang's dir,
# 'llvm-config --bindir', then PATH. When clang is the toolchain, the crossscripts
# llvm-config wrapper honours YOCTO_ALTERNATE_EXE_PATH and reports the target
# sysroot bindir, so clang-sys's 'llvm-config --bindir' step resolves to a target
# clang that cannot run on the build host (native bindgen then fails with
# "could not run executable .../clang-NN: No such file or directory", e.g. when
# building mesa with the rusticl/opencl PACKAGECONFIG). Set CLANG_PATH to the
# native clang so the runnable host binary is used first.
