This seems likely to be a mips*-specific bug in Mesa's llvmpipe or some
dependency of llvmpipe (maybe LLVM?), rather than directly a GTK bug: I
can avoid the test failure by running tests with GALLIUM_DRIVER=softpipe
and LIBGL_ALWAYS_SOFTWARE=true in the environment.

I've set up the GTK build to use GALLIUM_DRIVER=softpipe and
LIBGL_ALWAYS_SOFTWARE=true for build-time tests, and I don't intend to
investigate this further from GTK's point of view. Investigation by the
mips porting team would be appreciated.
