Yes, I realize that and documented it in the patch ... but I also tested on pre-5.19 kernels and what I have in the patch works. Did it not work in your testing ? > (see kernel patch [1]), so we need a way to call 'pkg-config --static' > with pre-5.19 kernels.

Also considered and discarded. As do the dynamically linked ones for the c runtime. We aren't talking about using these outside of a single build and they are generated on the fly, so again, there's very little concern about runtimes changing after linking.. There's less risk in static than in the alternatives.
