do not build tail_build modules outside of tail_build

There are several modules in tail_build now that are depended on by
other modules from postprocess (e.g., pyuno depends on 18npool). That
means that build.pl actually schedules i18npool (and its parents) for
build. This is fine for build.pl -P1, but it could be a problem for
build.pl -P2. It is also wasteful, because we are not actually using
tail_build to the full extent.

This gross hack schedules all modules that depend on any tail_build
module _after_ tail_build, so all modules that are in tail_build are
only build in tail_build.
