Looks like you are mising a generated Makefile ? Possibly try to make clean and ./autogen.sh again before make.
Or if nothing helps, do a fresh clone. The following should do:
git clone https://git.xfce.org/xfce/thunar --branch thunar-1.8.4 cd thunar curl https://git.xfce.org/xfce/thunar/patch/?id=9004a8237c4192f54e32a38e29ee29f625d72e2a | git am ./autogen.sh make
