    Subject[PATCH 5.4 08/71] kbuild: add CONFIG_LD_IS_LLD
    Date
    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.
