[Spice-devel] [spice-gtk] automake: Disable portability warnings

[Christophe Fergeau]

When they are enabled, autogen.sh fails with:

autoreconf: automake failed with exit status: 1

on my F19.
-Wportability used to be automatically disabled with automake <= 1.12 when using
silent rules, but this is no longer the case with automake 1.13 which is what
fedora 19 uses: http://www.flameeyes.eu/autotools-mythbuster/automake/silent.html
"As of version 1.13, though, this opt-in is no longer necessary, as all the
Makefiles are generated to support them. The silent-rules option is now a
no-op, doing nothing at all, in particular not silencing the portability
warnings."

This commit disables these warnings in order to avoid autogen.sh breakage
because of the use of -Werror, they can be reenabled once gtk-doc.make is
fixed to avoid these portability warnings.
