Actually, it is not lack of cleaning up:

dpkg-buildpackage calls the build targets and then the binary targets.

In the debian/rules for cjk, binary-indep depends on build-indep, so
when binary-indep is invoked, build-indep is executed again.

Because $(build_thaifonts) was already created the first time build-indep
was invoked, creating the directory again is what triggers the error.

Avoiding targets to be executed twice is precisely what stamp files
are used for. The attached patch (warning: not tested) might fix the problem.

Thanks.
