glables-3-batch pdf output very slow

[Luthor2k]

Running on a Pi 3 B+, Raspbian 9.9, strace glabels-3-batch takes about 17s to complete.

time strace glabels-3-batch --output=laser-label.pdf laser-label.glabels

shows all the templates are getting loaded from /usr/local/share/libglabels-3.0/templates and then gcc-arm-linux-gnueabihf is called and it takes a second to complete, for each template. I have moved the templates to /usr/local/share/libglabels-3.0/templates/stashed_templates, now time glabels-3-batch takes 0.5s to complete. This fixes the problem for me since I do not use templates.
*categories.xml and paper-sizes.xml had to be moved back to /usr/local/share/libglabels-3.0/templates to get the gui to boot again. This has not affected the batch time.
