vala: if no proper compiler found, set $(VALAC) to 'valac' This is better than setting it to ':' (as is currently done), because a triggered makefile rule invoking a vala compilation will then clearly fail with an informative error message like "valac: command not found", rather than silently, with the error possibly going unnoticed, or triggering harder-to-diagnose fallout failures in later steps. For a precedent of a similar behaviour, see the AC_PROG_YACC macro. * m4/valac.m4: Implement the new semantic. * doc/automake.texi (Vala Support): Document it. * t/vala4.sh: Adjust.
