But what magic does automake do with the variable INSTALL_DIRS?
EXTRA_DIST can just be added to as well, not much magic either.
fooman_MANS and foodoc_DATA come to mind as special variables,
if you are ok with having things installed by 'make install-data'
or plain 'make install'. I think this is what you really want,
but it doesn't totally fit this description:

OK, but you insist on the targets `man-pages' and `readme', you can just
put the whole block inside an if:
if MAN_PAGES
man-pages:
# do your stuff
else
man-pages:
# do nothing
fi

In that second case, you'd have to write all that manually.
