'select CRYPTO_AES' should 'select CRYPTO' automatically, I would hope.

This would result in a recursive dependency.

No, it wouldn't.  CRYPTO_AES depends on CRYPTO, which depends on nothing.

Thing is, CRYPTO_AES on only selectable on x86.

You're thinking about CRYPTO_AES_586. But looking at crypto/Kconfig, the dependencies are a bit weird:

        tristate "AES cipher algorithms"
        depends on CRYPTO && !(X86 && !X86_64)
config CRYPTO_AES_586
        tristate "AES cipher algorithms (i586)"
        depends on CRYPTO && (X86 && !X86_64)
