kbuild: add CONFIG_LD_IS_LLD
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.
