../meson.build:1:0: ERROR: Could not invoke sanity test executable: [Errno 8] Exec format error: '/builddir/python3-contourpy-1.1.1/.mesonpy-_m950dhd/meson-private/sanitycheckcpp.exe'.

Seems meson needs to be configured for cross build. However, `build_style=meson` + `build_helper=python3` doesn't work out of the box, and there is no build helper for meson... The only template using mesonpy seems to be scipy, which does `build_style=meson` + `build_helper=python3` but then needs custom `do_build()` and `do_install()`.

I rather prefer it there was a build helper for meson which fixes whatever is necessary for meson to build, if such a thing is possible...
