Some build flags are being passed by the build system: they're passed in a text
file called extra-bindgen-flags.in that's filled at configure time.
Other flags have to be inferred from the current target/host combination, in
Cranelift's build script directly. This is mostly cargo-culted from the
ServoBindings.toml file, and should probably be merged in the build system at
some point.
Some Windows-specific adjustments were needed to provide access to libclang for
bindgen support, by adding clang-cl to the plain Spidermonkey Windows builds.

Add an intermediate step in old-configure.in for setting up
BINDGEN_CFLAGS (renamed to BINDGEN_SYSTEM_FLAGS), so we can add whatever
flags we like (e.g. for system libaries with their includes in
non-standard places) at a later point.
When cross-compiling, rust-bindgen needs the -isysroot
flag we pass to the C++ compiler to find the correct
headers. Add a new BINDGEN_CFLAGS environment variable
for passing this and other relevant options, and reformat
its contents in toolchain.configure so we can use autoconf-
style template substitution to poke it into a bindgen.toml
file to be read by build scripts like build_gecko.rs.
Set this variable from the macosx/cross-mozconfig.common
to the same extra flags we pass to CXX so automation
builds work correctly with --enable-stylo.
