Mltiple target rules not recognized

[Stepan Kasal]

Hello,
  the standard targets provided by Automake can be overriden from
Makefile.am.  I tried the following:

install uninstall installcheck:
        : Do not run $@ in elfutils.

But automake did not notice that the rule redefines a standard rule.
But it was copied to Makefile.in, as expected.

Automake should recognize that the above redefines the three targets.

Have a nice day,
        Stepan Kasal
