globus-update-doxygen-index and globus-vararg-enums-doxygen-filter.pl are used
by doxygen. Some packages (such as the gaa package) have doxygen documentation
but don't depend on common, so configure fails when it attempts to do the
doxygen dependency check.

Probably one of the following should happen:
- move the scripts to core (everything depends on core, and the rest of the
doxygen stuff is there)
- make the doxygen autoconf stuff not fail if the dependencies checker can't be
run (this would break cross-module links, but if the package doesn't depend on
common, it probably doesn't have too many other modules to link to)
- add a compile-time dependency on the common pgm package in packages which do
not otherwise depend on common
