That's workable, but in that case you should realize that applications
link (dynamically) directly against libgcrypt beside linking directly
against libgnutls only, and they become dependent on the libgcrypt ABI.

Intermediate libraries like libldap will then have to become dependent
on the libgcrypt ABI, too, or pass it on to the next layer.  Something
to consider at least.

This might be softened somewhat by our use of versioned symbols, on
platforms that support it.
