/* The purpose of MBEDTLS_SOME_BUILTIN_EC is to signal that there are builtin
* curves so we want to make sure there is some code using them:
* - if there is at least one PSA_WANT_ALG_xxx which is not accelerated
* - if there is at least one builtin module/function (ex: PK_PARSE_EC_EXTENDED)
* that relies on these curves.
* If none of the above condition is met, then we forcedly enable builtin ECDSA,
* ECDH and ECJPAKE support.
