These tests were incorrect.  Patches have been posted to the piglit mailing list.

    arb_uniform_buffer_object: Only use row_major or column_major on matrix types
    
    OpenGL ES 3.0 requires that the row_major and column_major layout
    qualifiers only be accepted on matrix types.  Previously this test would
    put the layout qualifier on any type.

Following 5 piglit cases were fixed by piglit commit 630006e1b45fb7bfd5ed2c17f.
spec/ARB_uniform_buffer_object_dlist
spec/ARB_uniform_buffer_object_getactiveuniformsiv-uniform-array-stride
spec/ARB_uniform_buffer_object_getactiveuniformsiv-uniform-matrix-stride
spec/ARB_uniform_buffer_object_getactiveuniformsiv-uniform-type

But case spec/ARB_uniform_buffer_object_row-major still fails on latest mesa master and 9.1 branch.

This case was not mentioned in the original report, and it's pretty clearly a different issue.  Please keep separate bugs separate.  In other words, please open a new bug for this issue.
