On Patch [2006091320575529756]:
Stefan Fiedler:
	scripts/functions: fix the pkginstalled function to give reasonable
	results even for Crystal+AddOn targets.
	Without this fix, e.g. dbus-glib fails in Crystal builds if doxygen is
	an add-on package because doxygen is built only in stage 9 but dbus-glib
	tries to use it in stage 5.
	Furthermore I don't see any reason for pkginstalled() to have different
	meanings in stages < 9 and stage = 9.
