[Spice-devel] [PATCH spice] Disable -Waggregate-return if building with SLIRP

[Daniel P. Berrange]

From: "Daniel P. Berrange" <berrange at redhat.com>

The API design of SLIRP means that it is not practical to use
the -Waggregate-return warning flag. Disable this flag in the
(unlikely) scenario where SLIRP is actually requested at build
time
