Using https://github.com/shenki/op-build/commits/kernel-5.15.28-buildroot-2022.02 that uses GCC 10 and has some other fixes, we hit an error when linking:

We will work on supporting compilers past what is used now as time allows, but there is likely not much time to do so in the near future. If you can get it working I'll take a look at a patch. :-)
