Ok. But I would rather use mbed TLS as the default option:
        select BR2_PACKAGE_MBEDTLS if !BR2_PACKAGE_OPENSSL

OpenVPN + mbed TLS combination is well tested (Android/iOS builds use mbed TLS).

BTW, there is "--disable-crypto" build option, but I'm unsure if anyone use it.

P. S. What about other options? OpenWRT has lot of them

This helps make the binary more compact.
