Fix mutter build on i686

[Douglas R. Reno]

I received a report over email recently that mutter was broken on i686. I now have a moderately-fast (SBU=120) dual-core i686 system (Intel Core Duo w/ 4GB of RAM), and I'm going to fix this.

Moving to 8.4

I will test this with GNOME 3.30. If it turns out that there is still a problem, I'll also modify the errata for 8.3.

Still occurs with Mutter 3.30.

Hey Xi,

Just wanted to say thank you for confirming!

[Xi Ruoyao]

Adding configure option --enable-compile-warnings=minimum can workaround this (tested with mutter-3.30.0).

[Douglas R. Reno]

Minor changes in 3.30.5:
* Fix a bunch of compiler warnings that could prevent building (Ernestas Kulik)
* Fix location entry icon not reacting to clicks (Ernestas Kulik)

Might not even have to use that option!

I should have this done by the end of the week at the latest, with my Dell Latitude D820's current pace.

Note that large package builds are painful on this machine, so Qt5/WebKitGTK/rustc will take much longer than on my other systems (even my PPC is faster sometimes).

Time to go give that flag a shot.

That switch worked! Thanks again, Xi.
