1. Installation from download cache failed.
After investigation, we found that the copy() function (line 163) of /usr/share/phoronix-test-suite/pts-core/objects/pts_test_installer.php uses a context param which is always invalid. Remove this param will work around this issue.
2. The access mode of 'pts/test-resources/tremulous' is not enough for regular user access, which will block the installation of this case.
3. Crafty installation failed on 32bit linux due to the -DINLINE64 under 'Linux' category of the Makefile.
