This greatly shortens the 'make' output, making it more readable
and useful.  For example, on my platform it shortens a
4125-character line "gcc -std=gnu99 -c -Demacs -I. -I. -I../lib
... emacs.c" -- a line so long that it's hard to see what's going
on or where the diagnostics are -- to just "CC emacs.o".
* INSTALL: Document this.
* configure.ac: Add AM_SILENT_RULES([yes]).
(AM_DEFAULT_VERBOSITY): Remove now-unnecessary initialization.
* etc/NEWS: Document this.
Fixes: bug#19501

with 'make WERROR_CFLAGS=' so that the warnings are not treated as
errors.
Use --enable-silent-rules to cause 'make' to chatter less. This is
helpful when combined with options like --enable-gcc-warnings that
generate long shell-command lines. 'make V=0' also suppresses the
chatter.
Use --disable-silent-rules to cause 'make' to give more details about
the commands it executes. This can be helpful when debugging a build
that goes awry. 'make V=1' also enables the extra chatter.
Use --enable-link-time-optimization to enable link-time optimizer. If
you're using GNU compiler, this feature is supported since version 4.5.0.

** The configure option `--with-pkg-config-prog' has been removed.
Use './configure PKG_CONFIG=/full/name/of/pkg-config' if you need to.
** The configure option '--enable-silent-rules' and the command
'make V=0' now do a better job of suppressing chatter.
** The configure option '--enable-silent-rules' is now the default,
and silent rules are now quieter. To get the old behavior where
'make' chatters a lot, configure with '--disable-silent-rules' or
build with 'make V=1'.
