We have: $(if $(RSA_DEP),$<,$(CONFIG_CRYPTO_RSA_KEY)) '$<' is the first dependency which is $(RSA_DEP). $(RSA_DEP) is either empty (in which case $(CONFIG_CRYPTO_RSA_KEY) is used), or set to $(CONFIG_CRYPTO_RSA_KEY) a few lines up. so all this is a complicated way of using $(CONFIG_CRYPTO_RSA_KEY) directly.
