Comment:
There was an issue with cross building `python3-rpds-py` that is now solved.
For the record, this needed `build_helper=rust` and
```
if [ "$CROSS_BUILD" ]; then
	makedepends="python3 rust-std"
	export PYO3_CROSS_LIB_DIR="${XBPS_CROSS_BASE}/usr/lib"
	export PYO3_CROSS_INCLUDE_DIR="${XBPS_CROSS_BASE}/usr/include"
fi
```
which I took from `python3-adblock`.

I wonder if the `PYO3_CROSS...` variables should go into the rust build_helper (this is repeated in 4 and now 5 templates).
