Default to 'configure --enable-silent-rules'
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

-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

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.
