From the way it was done in Gentoo, I assume this is not needed?
mbedtls is a separate package, and I have libressl as the curlssl provider,
which is a curl built against libressl.

My initial comment was a bit out of place, but I just assume it will
justwork™ on guix, otherwise a curl-with-mbedtls would have to be
created.

Sorry for the confusion.
