Subject[PATCH v2 1/3] kbuild: add CONFIG_LD_IS_LLD
Date
From: Sami Tolvanen <samitolvanen@google.com>

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.
