  1. configure.ac: use silent rules if available 

    Using silent rules gives a cleaner output from the build.  This makes it
trivially easy to spot warnings.  The original, verbose, output can still
be seen by doing one of these...

$ ./configure --disable-silent-rules && make

...or...

$ ./configure && make V=1

...otherwise the build output looks like this...

$ ./configure && make
  CC       thirdparty/libtap_a-tap.o
  AR       libtap.a
  CC       watchman-argv.o
  CC       watchman-opt.o
  CC       watchman-cfg.o
  CC       watchman-log.o
  CC       watchman-json.o
  CC       watchman-bser.o
  CC       watchman-hash.o
  CC       watchman-ht.o

  2. configure.ac: output extra build config summery to console 

    It's sometimes useful, and always harmless, to output some extra config
summery at the end of the configure script.  It'll save some debugging time
if your eye catches the -O2 in the CFLAGS before you set out to debug.
When that happened, you'd reconfigure with CFLAGS=-g and continue.

The output looks like this...

...
config.status: creating Makefile
config.status: creating thirdparty/jansson/jansson_config.h
config.status: creating config.h
config.status: config.h is unchanged
config.status: executing depfiles commands

Your build configuration:

        CPPFLAGS =  -D_REENTRANT -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE
        CFLAGS = -g -O2 -I/usr/local/Cellar/pcre/8.33/include -Wall -Wextra -Wdeclaration-after-statement -g -gdwarf-2 -fno-omit-frame-pointer
        LDFLAGS =
        prefix: /usr/local
        version: 2.9.5

  3. move foreign option from autogen.sh to Makefile.am 

    $ ./autogen.sh

...generates the build system just fine, but...

$ autoreconv -i

...should also work.  Both work if the foreign option is specified in
Makefile.am instead of on the command line to automake in autogen.sh.

The reason to ensure autoreconf works is to reduce the dependency on having
the extra autogen.sh script to get the build system going.

With this change, ./autogen.sh and autoreconf -i are the same...

$ autoreconf -i
