automake-1.4-p2 installdirs target bug

[Bruno Haible]

Hi,

If an "installdir-local" target is added to a Makefile.am, "make
installdirs" will not execute it, violating the documentation which
says

    "However, various useful
    targets have a `-local' version you can specify in your `Makefile.in'.
    Automake will supplement the standard target with these user-supplied
    targets."

I need to explicitly add

installdirs: installdirs-local

but I think automake should generate that dependency itself.

To reproduce:
- take gettext-0.10.38,
- remove the last three lines of doc/Makefile.am (which contain a
  workaround to this bug)
- run "automake --gnits --include-deps Makefile misc/Makefile tests/Makefile"
- run "autoconf" (from autoconf-2.13)

Then "make installdirs" will not create the $(htmldir).
