As you can see there, LOCATION_NAME is not an environment variable, but a
GRASS variable stored in $GISRC. The relevant code sniplet is

-->
# Set the global grassrc file to individual file name
MYGISRC="$HOME/.grassrc.$GRASS_VERSION.$$"

echo "GISDBASE: $MYGISDBASE" > "$MYGISRC"
echo "LOCATION_NAME: $MYLOC" >> "$MYGISRC"
echo "MAPSET: $MYMAPSET" >> "$MYGISRC"
echo "GRASS_GUI: text" >> "$MYGISRC"

# path to GRASS settings file
export GISRC=$MYGISRC
<--
