  install: don't create empty dirs when an empty 'foo_PRIMARY' is used
  
  Fixes automake bug#11030 and bug#10997.
  
  An empty declaration of "foo_PRIMARY" in a Makefile.am used to
  cause the generated install rules to create the directory $(foodir)
  anyway, even if nothing was to be installed there.
  
  While this could be seen as a convenient way to create a $(foodir)
  directory upon "make install" (respecting $(DESTDIR) settings and
  such), it also caused problems with conditionals; for example, an
  input of:
  
    if FALSE
    pgkdata_DATA = something
    endif
  
  caused the generated install rules to unconditionally create the
  $(pkgdatadir) directory (see automake bug#10997).
  
  Also, a user wanting to create an empty directory upon installation
  can easily do so with a custom install hook, as in:
  
    installdirs-local:
            $(MKDIR_P) $(DESTDIR)$(foodir)
    install-data-hook: installdirs-local
  
  On the other hand, the old behavior of "always create $(foodir),
  even if 'foo_PRIMARY' is empty" was harder and more tricky to
  override.
  
  Thus, from now on, an empty declaration of "foo_PRIMARY" will not
  cause the directory $(foodir) to be created upon "make install"
  anymore.

  lib/am/ltlib.am, lib/am/mans.am, lib/am/progs.am, lib/am/python.am,

  creating an installation directory if no files are actually to be
  installed there.
  * tests/instdir-empty.test: Remove, it was testing a semantic
  opposite to the one we now want and implement.
  * tests/instdir-no-empty.test: New test, check the new semantic.
  * tests/instdir-cond.test: Enhance.  Move the still-failing part
  of the test ...
  * tests/instdir-cond2.test: ... here.
  * tests/list-of-tests.mk, tests/Makefile.am (XFAIL_TESTS): Update.
  * tests/java3.test: Adjust to avoid spurious failures.
