In the case of ‘meson-build-system’, the logical fix IMO would be to
define ‘%build-inputs‘, ‘%outputs’, etc. when cross-compiling, with the
patch below.

This would be consistent with the fact that ‘meson-build-system’ defines
those variables for native builds already.

Thoughts?

Longer-term we can move away from ‘%outputs’, ‘%build-inputs’, & co.,
but that’s another story.
