I copied and pasted this command which was giving me crashes, and now it's
not running any tests.  Git logs don't seem to show any relevant changes.

$ git clean -xfd
$ ./autogen.sh && make && echo worked
$ cd test

And I have this running (and killed and restarted after to verify it wasn't
in a weird state):  
while : ; do Xvfb -screen 0 1680x1024x24 -ac -nolisten tcp :5; done


cairo-test-suite without an argument does run stuff.  Running it with a
different argument works:

$ DISPLAY=:5 CAIRO_TEST_TARGET=xcb ./cairo-test-suite pthread-show-text
