Since this is a choice, either one is selected. Which means SSL support
seems to be not optional.

In that case I would prefer we use something like:

    config BR2_PACKAGE_SHAIRPORT_SYNC
        bool "shairport-sync"
        # Dependencies and selects as above
        select BR2_PACKAGE_POLARSSL if !BR2_PACKAGE_OPENSSL

This way, we ensure at least one SSL implementation is available, and do
not bother the user with a useless prompt.

There is no tinysvcmdns packaged in Buildroot. Does shairport-sync
bundles its own version? Otherwise, I've seen there is a tinysvcmdns
package on bitbucket: https://bitbucket.org/geekman/tinysvcmdns
Maybe it would be interesting to package it in Buildroot?

If so, I would just remove the choice altogether, and just use
tinysvcmdns if avahi is not enabled.

There, you need to select BR2_PACKAGE_LIBSOXR.

Obviously, adapt the .mk to the above comments.
