meson.build files that use cc.run() in native builds can silently fallback to
meson.get_cross_property() in cross builds without an exe-wrapper, but there's
no way to know that this is happening.
As the defaults may be pessimistic (for example, disabling the support for a
feature that should be enabled) emit a warning when the default is used, so that
the recipe can explicitly set the cross property as relevant.
