* The insecure implementation of mbedtls_psa_external_get_random() is
* disabled by default.
* When MBEDTLS_PSA_CRYPTO_EXTERNAL_RNG is enabled and the test
* helpers are linked into a program, you must enable this before running any
* code that uses the PSA subsystem to generate random data (including internal
* random generation for purposes such as blinding when the random generation
* is routed through PSA).
* You can enable and disable it at any time, regardless of the state
* of the PSA subsystem. You may disable it temporarily to simulate a
* depleted entropy source.
