Thank you for taking the time to file a bug report. The two examples you cite are more likely to be due to a discrepancy in the font used on your system (i.e. it is not an exact match to the one used to generate the reference image). Having no display available will just prevent the xlib backend from being tested, but should not cause a failure. If that's symptomatic of the errors detected during make check, then it would appear that cairo has been sucessfully built on your system -- though I would strongly recommend that you update to the latest stable release (1.8.6).
