Subject: [PATCH] Add an error message in case of invalid configured dependency
 mbedTLS. (#3364)

Especially if the user wants to use the library as component in IDF,
there are some pitfalls while doing make menuconfig. One is this missing
dependency which will now fail with a better error message with a hint to
the user how to fix it.
