Sigh, I liked this idea, but it wouldn't work.  The reason is that
many gnulib modules use AC_REPLACE_FUNCS, so you can't have more than
one directory that use @LTLIBOBJS@ without adding the same file to
every such directory.  The AC_REPLACE_FUNCS interface is inflexible,
IMHO.

Having two configure.ac is a solution, but for libidn, where the
library consists of maybe 10 files, and the command line tool maybe 3
files, it seem rather wasteful.  Running two configure.ac is really
slow, and causes other problems as well (like generating two config.h
files -- sometimes you need settings from two config.h...).

Ideas appreciated,
Simon
