Poky calls host pzstd with uninative's libstdc++.so.6 instead of the host library

Hello,

I'm a newbie to Yocto Linux and I am attempting to build a vendor BSP
on an unsupported distribution: Fedora 40.

The OS' libstdc++.so.6 provides CXXABI_1.3.15 vs uninative's which
provides up to CXXABI_1.3.14. That would be fine, if the
sstate_archive_package would not attempt to attempt to run it in an ENV
that forces uninative's library.

Question 1:
Using bitbake -e and reading the logs I was already able to get this
far. How can I understand what the ENV, that the script executes in
looks like?

Question 2:
Is this a bug in the vendor BSP or is Poky just silly mixing and
matching host tools build against the OS toolchain and uninative's
libraries as it pleases?

Regards

Tamara Schmitz
