[PATCH 02/11] Makefile: Drop warn-stack-size plugin opt

From: Nathan Chancellor
Date: Thu Jan 25 2024 - 17:56:22 EST


Now that the minimum supported version of LLVM for building the kernel
has been bumped to 13.0.1, the inner ifeq statement is always false, as
the build will fail during the configuration stage for older LLVM
versions.

This effectively reverts commit 24845dcb170e ("Makefile: LTO: have
linker check -Wframe-larger-than") and its follow up fix,
commit 0236526d76b8 ("Makefile: lto: Pass -warn-stack-size only on LLD <
13.0.0").
