There is no regular testing of headless-only. However, the only test 
needed for this fix was a single confirmation that the headless 
libraries indeed compile even without X_CFLAGS and X_LIBS. (This was 
apparent from the code since the make rules did not use X_CFLAGS and 
X_LIBS, but just to be 100% sure, I also tried building it.)
