The stable version (one available at Ubuntu) doesn't have any GLES support, and the build failure probably happens because now Qt is compiled with the GLES backend.
Current upstream implements some support for GLES, but the performance is terrible, so even if we port the patches, it'll have no use.
So to fix this bug we should just disable OpenGL support when compiling for armel.
