Just set the CC environment variable eg export CC=icc

I've tried it once in the past, but not for many years. It should mostly
work since icc claims strong compatibility with gcc.

GNUTLS is used to provide TLS encryption for libvirtd TCP sockets.
Libvirt can alternatively use cyrus-sasl for Kerberos based encryption
and authentication. Failing that you'd have to use an SSH tunnel to
access the libvirt RPC API remotely.

macvtap has no impact on the client library.
