Subject: Makefile: Add prefix variables for silencing commands.

* Makefile.am (CCWL_GEN*, CWLTOOL_GEN*, DOT_GEN*, EMACS_GEN*,
GUILD_GEN*, SKRIBILO_GEN*): New variables.
(%.go): Prefix with GUILD_GEN instead of AM_V_GEN.
($(SKRIBILO_BUILD_DIR)/%.cwl): Prefix with CCWL_GEN instead of
AM_V_GEN.
(%.dot): Prefix with CWLTOOL_GEN instead of AM_V_GEN.
(%.svg): Prefix with DOT_GEN.
($(SKRIBILO_BUILD_DIR)/ccwl.info, $(SKRIBILO_BUILD_DIR)/ccwl.html):
Prefix with SKRIBILO_GEN instead of AM_V_GEN.
