Built piglit from git-master (67675034486e29ecbc4a4da2fc74b184d7d11cb8) and wanted to run the testsuite on my PowerMac G5 + Radeon HD 6450 (ppc64, big endian). However 2 sanity tests fail (with mesa 18.1.5 and mesa 18.0.5). This might be a regression in piglit, 'cause piglit passed sanity tests on the same system at the time mesa 18.0.0 was released.

For more info see bug #107448.
