I still don't get what is the plan for this virtual package. We have
two options:

 - Make it a regular virtual package, like package/opengl/libgles/.
   However in this case, we must change all packages that need
   OpenSSL/LibreSSL to use a "depends on BR2_PACKAGE_LIBSSL", which is
   a bit annoying.

 - Make it a virtual package like package/jpeg/, where it has a choice
   to define which jpeg implementation should be used. This nicely
   allows packages to "select BR2_PACKAGE_LIBSSL".

Also, how are we going to handle the fact that some packages support
only OpenSSL, while some support both OpenSSL and LibreSSL.

Even if all of this doesn't get implemented in the first series, I
still would like to understand what the plan is.

Best regards,

Thomas
