automake silent-rules feature is not compatible with --disable-dependency-tracking

[Dmitry V. Levin]

Hi,

There seems to be a bug in automake: silent-rules support is not
compatible with --disable-dependency-tracking yet.  Passing this option to
configure results to garbage both in silent and verbose output.
Here is a reproducer on GNU/Linux:

$ automake --version |head -1
automake (GNU automake) 1.11.1
$ cat configure.ac 
AC_INIT([foo],[0])
AM_CONFIG_HEADER([config.h])
AM_INIT_AUTOMAKE([silent-rules])
AC_PROG_CC
AC_CONFIG_FILES([Makefile])
AC_OUTPUT
$ cat Makefile.am 
bin_PROGRAMS = foo
$ cat foo.c 
int main(){return 0;}
$ touch NEWS README AUTHORS ChangeLog INSTALL COPYING
$ aclocal && autoconf && autoheader && automake --add-missing
configure.ac:3: installing `./install-sh'
configure.ac:3: installing `./missing'
Makefile.am: installing `./depcomp'
