I suspect this is resulting in:

WARNING: rust-1.63.0-r0 do_package_qa: QA Issue: File /usr/lib/librustc_driver-f2e4e0d5a644441f.so in package rust contains reference to TMPDIR [buildpaths]

https://autobuilder.yoctoproject.org/typhoon/#/builders/52/builds/5731
https://autobuilder.yoctoproject.org/typhoon/#/builders/64/builds/5809

and more. Certainly one of the patches is causing this :(

Cheers,

Richard
