Make 4.3 gives white space warning

[psd]

$ make
Makefile:12: extraneous text after 'else' directive

$ make --version
GNU Make 4.3
Built for x86_64-pc-linux-gnu

Also the SPATIAL to find the shared library installed might not work in the way intended:

digital-land-python/Makefile

Line 13 in 18c44d5

SPATIAL := $(shell ls /usr/lib/x86_64-linux-gnu/*spatialite* 2> /dev/null)

There's always more than one file matching that pattern, more on a machine that's been updated:

$ ls /usr/lib/x86_64-linux-gnu/*spatialite*
/usr/lib/x86_64-linux-gnu/libspatialite.so.8	  /usr/lib/x86_64-linux-gnu/mod_spatialite.so	 /usr/lib/x86_64-linux-gnu/mod_spatialite.so.8.1.0
/usr/lib/x86_64-linux-gnu/libspatialite.so.8.1.0  /usr/lib/x86_64-linux-gnu/mod_spatialite.so.8

Suggest replacing the wildcard with just mod_spatialite.so
