Comment # 29 on bug 952324 from Dave Plater

The solution for audacity is an update to version 2.1.2 which builds with
wxGTK3-3_0 and doesn't need a custom find provides. This also requires an
update to wxWidgets3-3_0's linked wxGTK3-3_0 package because audacity-2.1.2
doesn't build with a wxGTK3-3_0 built with --enable-stl.
