It can be set by the configure script so that it affects even the
top-level make invocation.

It can be used to give some indication of the progress of the build
without echoing the actual commands: AM_PFX="@echo $@; "

It might be more portable.  I'm not sure how portable the -s flag is.

There's no reason it couldn't be done for texinfos and other things also.
 I wasn't sure if it would be useful, so I didn't add it.  How likely is
it that the build command for texinfo stuff will exceed a line or two?
