Can we run this test on android? If not then it should be explained in the
comments. Also it's better to always compile the test, but skip it if it doesn't
work on the current platform. I.e. replace this condition in the build file with
an #ifdef in the test source.

Managed to get it compiled on all platforms. It is safe as long as it compiles
and no OpenGL function calls happen during the test.
