Changes since 1.144: +12 -6 lines
allow gtkdoc steps to be skipped if the tools are not installed #419979 -- if packages want these steps, they can DEPEND on the pkg in question; similarly, give a blanket pass to autopoint for embedded/USE=-nls systems that do not install the gettext package #417641
