automake and AC_CONFIG_FILES($foo)

[Harlan Stenn]

autoconf handles AC_CONFIG_FILES($foo) properly.

A plain invocation of "automake" rightly complains that it has no idea what
it needs to look at, but running "automake (some list of Makefiles)"
produces:

        configure.ac: 23: required file `./$foo.in' not found

which seems wrong.  If automake is called with explicit filename arguments
it should ignore (or not complain) about variables in AC_CONFIG_FILES.
