Kconfiglib fails to correctly parse the "newer" Kconfig.include files that are used from kernel 5.12.1 and upwards. To reproduce, simply download a recent kernel, and run something like this:
You will be getting an error, stating that there seems to be a linker support error, although running make works just fine with the same environment. For reference, this was tested on a clean gentoo installation (on 2021-08-09) with kernel 5.13.8-gentoo.
