The current CVS autoconf does not "make install" properly if builddir !=
srcdir.
The following fragment is from man/Makefile:
...
# Independent from this package.
config.guess.1: $(srcdir)/config.guess.x $(top_srcdir)/config.guess
config.sub.1: $(srcdir)/config.sub.x $(top_srcdir)/config.sub
.x.1:
@if test -f $(top_builddir)/$*; then \
If the package is being built outside of the source tree, the .x.1 rule
looks for the programs in top_builddir, but the dependency lines look
for the programs in srcdir.
