Empty check_PROGRAMS causes "make all" to be called

[Stepan Kasal]

Hello,
  I encountered a problem.  If Makefile.am contains:

check_PROGRAMS =
check_SCRIPTS =
TESTS = ....

then the generated makefile contains:

check-am: all-am
        $(MAKE) $(AM_MAKEFLAGS) $(check_PROGRAMS) $(check_SCRIPTS)
        $(MAKE) $(AM_MAKEFLAGS) check-TESTS

Beacuse the two variables are empty, the first call to make is
effectively "make all", causing recursive traversal of the whole
subtree.

One possible fix seems to be to combine the two calls to one:

check-am: all-am
        $(MAKE) $(AM_MAKEFLAGS) $(check_PROGRAMS) $(check_SCRIPTS) \
                check-TESTS

What do you think?

Have a nice day,
        Stepan
