According to the official requirements, bindgen needs libclang to
parse C/C++ headers. libclang is loaded at runtime by bindgen, which
is why we didn't notice any build issue. However, using bindgen on a
simple header file blows up:
thread 'main' panicked at bindgen/lib.rs:616:27:
Unable to find libclang: "couldn't find any valid shared libraries matching: ['libclang.so', 'libclang-*.so', 'libclang.so.*', 'libclang-*.so.*'], s
et the `LIBCLANG_PATH` environment variable to a path where one of these files can be found (invalid: [])"
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
So far, bindgen was only used by mesa3d, and it turns out that mesa3d
also depends on clang, which pulls in host-clang, so the problem was
not visible. However, as we're about to use bindgen for other
things (namely Rust support in Linux), this issue needs to be fixed.
