Re: [libvirt] [PATCH] qemu: Check for gnutls_rnd() explicitly

Our use of gnutls_rnd() is conditional to the availability of the <gnutls/crypto.h> header file. Such check, however, turns out not to be strict enough as there are some versions of gnutls (eg. 2.8.5 as available in CentOS 6) that provide the header file, but not the function itself, which was introduced in 2.12.0. Introduce an explicit check for the function itself. --- Would qualify as a build breaker (see [1]) but I'd rather have some feedback before pushing it.
