Change subject: Improve error message when libosmocom directory cannot be found.
......................................................................


Improve error message when libosmocom directory cannot be found.

The rules in build/Makefile.vty-reference.inc require a libosmocore
source tree. Make the top-level Makefile check that LIBOSMO_DIR is
set to a valid directory before running the build.

This transforms an obscure build error into:

Directory '~/source/gsm/libosmocore' not found, please set LIBOSMO_DIR to
the path of your libosmocom source tree: make LIBOSMO_DIR=/path/to/libosmocore
Makefile:80: recipe for target 'check-deps' failed
