Nice one, pushed as b452fe87e0c6e7634a2cb44274fa46832c763b40.

On non-x86_64 platforms, gtk+ is linked with a gdk-pixbuf version that
doesn’t support SVG.  This causes the ‘icontheme’ test to fail because it
tries to fetch SVG icons in some of the tests.

Therefore, we need to disable the test when SVG support isn’t available.

* gnu/packages/gtk.scm (gtk+)[propagated-inputs]: Use the ‘target-x86-64?’
convenience function.
[arguments]<#:phases>{disable-failing-tests}: Disable ‘icontheme’ test on
non-x86_64 platforms.

Hello,

This patch doesn’t change the gtk+ output derivations on x86_64-linux, so
it won’t cause any rebuilds there.

And together with the one in issue 50521, it allows gtk+ to build on
powerpc64le-linux. In fact, I can even build GTK+ apps such as Emacs and
Transmission! Unfortunately, GNOME apps need SVG support because of the
icon theme. And rust doesn’t build on powerpc64le-linux (mrustc errors out
with “Unknown target name ''”).

Thanks,
Thiago
