They're must likely buggy, or more precisely misdesigned.

The gnome-doc-utils should be generally treated as separate
build-time tool and maybe has to be fix to support sysroot.

There is no really generic solution, but just a few rules,
eg. full sysroot support and strictly differentiating between
build-time and target code (eg. bundled/builtin code generators).
