Add bindings_rs target for generating rust bindings to target-independent qemu C APIs. The bindings need be created before any rust crate that uses them is compiled. The bindings.rs file will end up in BUILDDIR/bindings.rs and have the same name as a target: ninja bindings.rs Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Manos Pitsidianakis <manos.pitsidianakis@linaro.org> Link: https://lore.kernel.org/r/1be89a27719049b7203eaf2eca8bbb75b33f18d4.1727961605.git.manos.pitsidianakis@linaro.org Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>pull/272/head
