	  Enable this option to re-include crypt() support for the SHA256, SHA512 and
	  Blowfish ciphers. Without this option, attempting to hash a string with a salt
	  requesting one of these ciphers will cause the crypt() function to call stub
	  implementations which will always fail with errno ENOSYS. Including the ciphers
	  will increase the library size by about 14KB after LZMA compression.
musl: improve crypt() size hack Instead of silently downgrading any non-MD5 crypt() request to DES, cleanly fail with return NULL and errno = ENOSYS. This allows callers to notice the missing support instead of the unwanted silent fallback to DES. Also add a menuconfig toolchain option to optionally disable the crypt size hack completely. This can be probably made dependant on SMALL_FLASH or a similar feature indicator in a future commit.
