Subject: [PATCH stable-v5.4 v2 1/2] kbuild: add CONFIG_LD_IS_LLD
Date: Fri, 25 Jun 2021 15:48:35 +0800	[thread overview]
Message-ID: <20210625154836.382536b1@xhacker.debian> (raw)
In-Reply-To: <20210625154737.3d64a434@xhacker.debian>

From: Sami Tolvanen <samitolvanen@google.com>

commit b744b43f79cc758127042e71f9ad7b1afda30f84 upstream.

Similarly to the CC_IS_CLANG config, add LD_IS_LLD to avoid GNU ld
specific logic such as ld-version or ld-ifversion and gain the
ability to select potential features that depend on the linker at
configuration time such as LTO.
