Per http://www.open-mpi.org/community/lists/devel/2009/10/7025.php,

use the new Automake "silent rules" if available.

If you are using an Automake prior to v1.11, you won't see the new 
silent rules -- it will automatically default back to the "verbose" 
rules.

Note, too, that even with these changes, you can enable the verbose 
"make all" output in one of two ways:

1. Add "V=1" to your "make" command line

{{{
shell$ make all V=1
}}}

2. Add "--disable-silent-rules" to your "configure" command line:

{{{
shell$ ./configure --disable-silent-rules ...
}}}

The one down side of using the silent rules by default is that we'll 
get less diagnostic information when users send their build logs.  I 
think we should update the web page to request that users send build 
logs of "make V=1", but I'm guessing that not everyone will do it.

Note that I did ''not'' silent-ize the libltdl build (which is a dozen
or so files in the beginning of the build) because we wholly import
libltdl at autogen time.  I therefore didn't want to patch libltdl
(further) after importing it a) to remain as forward- compatible as
possible, and b) patching the imported libltdl build system might be
tricky in terms of timestamps / dependencies.  So those dozen-or-so
files will still be "verbose", but the rest of the files in OMPI will
be "silent".

This commit was SVN r22189.
