Adjust the catch-all target at the end of the Makefile that is supposed
to route all unknown targets to sphinx, so it doesn't do this for the
shrink target. The shrink target has recently been added to
Makefile.common.inc in osmo-gsm-manuals, which gets included right above
the catch-all target. So it isn't an unknown target, but for some reason
the sphinx catch-all runs in addition to the shrink target (runs
shrink-pdfs.sh, see output below) and fails. As I did not add the
catch-all logic, preserve it but add an exception for the shrink rule.
Fix for:
+ make -C docs publish publish-html
make: Entering directory '/build/docs'
/opt/osmo-gsm-manuals/build/shrink-pdfs.sh _build/latex/osmopysim-usermanual.pdf
* _build/latex/osmopysim-usermanual.pdf: 272K (shrunk from 336K)
