Building from scratch fails due to attempt to delete non-existing gluon branch "patched"

[jj-freifunk-muc]

Checked out a fresh, clean copy of tag v2019.0.4, then tried to build from scratch, but build fails almost at the beginning:

[user@node001 site-ffm.test2]$ make

#########################
# FFMUC Firmware build
# Building release v2019.0.4 for branch stable

make manifest
make[1]: Entering directory `/home/user/site-ffm.test2'
rm -rf output
(cd gluon-build \
        && git remote set-url origin https://github.com/freifunk-gluon/gluon.git \
        && git fetch origin \
        && git checkout -q v2018.2.1)
ln -sfT .. gluon-build/site
make gluon-patch
make[2]: Entering directory `/home/user/site-ffm.test2'
echo "Applying Patches ..."
Applying Patches ...
(cd gluon-build; git branch -D patched)
error: branch 'patched' not found.
make[2]: *** [gluon-patch] Error 1
make[2]: Leaving directory `/home/user/site-ffm.test2'
make[1]: *** [gluon-prepare] Error 2
make[1]: Leaving directory `/home/user/site-ffm.test2'
make: *** [all] Error 2

Manually creating a branch called "patched" in the repo inside the gluon-build directory works around the issue and allows the build to move forward.

It's a known issue.

We maybe should move from the old and often patched Makefile to a buildscript of another community.
