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.

installed there.

opposite to the one we now want and implement.

of the test ...
