We've had a similar suggestion last month (thread partly in this mailing
list, partly in the libtool at gnu.org list, subject `libtool --silent
based on MAKEFLAGS?').  We've come to the conclusion that it would be
better not to abuse other tools' flags (in this case: MAKEFLAGS is for
make), but adjust Automake to call libtool with LIBTOOLFLAGS.

So you can get the same effect with
  make -s LIBTOOLFLAGS=--silent

or you can even
  .../configure LIBTOOLFLAGS=--silent MAKEFLAGS=-s

if your Automake is recent (for now you'll have to stick with the CVS
version, I'm afraid).

Besides, I cannot resist nitpicking:

This assumes a certain `make' program -- portable reading of MAKEFLAGS
has been explored in the December thread as well.
