Yeah, I had noticed this, and it is somewhat ugly. Instead of fixing every script, I want to terminate Kconfig in the very beginning of the parse stage. https://patchwork.kernel.org/patch/10936811/ I still see some "/bin/sh: 1: foogcc: not found" in the build stage, but not fixing up every $(shell ...) calls since displaying some warnings is not a big deal.
