`pkgsCross.aarch64-multiplatform.wlroots` fails to build

[colemickens]

Steps To Reproduce

For whatever reason, building sway natively for x86_64-linux works, but cross building aarch64-linux on an x86_64-linux host fails, with meson complaining it couldn't find hwdata via pkg-config.

Things generally look "fine" to me, so I'm not sure what the issue is.

• sway uses sway-unwrapped
• sway-unwrapped is built with wlroots-0.17
• wlroots-0.17 clearly includes hwdata as a buildInput

Would be nice to have this cross-compiling again. Happy to try some things if anyone has suggestions.

This repros with current nixos-unstable: 58a1abdb
