As I've said before, we should not be doing this. At all. We cannot reliably run build.rs, the garden path of cases that actually (and really slowly) manage to successfully run also do not need to be a build.rs so using meson/meson.build will be a superior experience, etc.
The system-deps patch does look quite nice though :) and it's very good that we can do it without build.rs.

Basically, what you actually want is rust-lang/cargo#7178 and to have people opt into that via run_command(), which we already document as an escape hatch to do whatever you want as long as meson doesn't take responsibility for it.
This returns --target value from rustc command line, or the native target.
