The HAVE_ARCH Kconfig options in lib/crypto try to solve the modular versus built-in problem, but it still fails when the the LIB option (e.g., CRYPTO_LIB_CURVE25519) is selected externally. Fix this by introducing a level of indirection with ARCH_MAY_HAVE Kconfig options, these then go on to select the ARCH_HAVE options if the ARCH Kconfig options matches that of the LIB option.
