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 Change-Id: Ic201373df115bb6f8c9a2bc30d18ff4c2a660deb Related: OS#2787
