coverage: an empty foo_PRIMARY should create directory $(foodir)

For example, a Makefile.am containing the definition:

  pkgdata_DATA =

should cause the 'install' rule of the generated Makefile.in to
create the '$(pkgdatadir)' directory (respecting any DESTDIR
setting as well).

Suggestion by Peter Breitenlohner in automake bug#10997.
