[PATCH 5.12 187/242] docs: Makefile: Use CONFIG_SHELL not SHELL

From: Kees Cook <keescook@chromium.org>

commit 222a28edce38b62074a950fb243df621c602b4d3 upstream.

Fix think-o about which variable to find the Kbuild-configured shell.
This has accidentally worked due to most shells setting $SHELL by
default.

Fixes: 51e46c7a4007 ("docs, parallelism: Rearrange how jobserver reservations are made")
