[PATCH] build: use automake's new $(AM_V_GEN) and $(AM_V_at) variables

[Jim Meyering]

With the change below, the default build output for generated
files in src/ is slightly more succinct:

  $ cd src && make
   GEN  wheel.h
   GEN  wheel-size.h
   GEN  version.h
   GEN  version.c
   GEN  fs.h
  make  all-am
  make[1]: Entering directory `/h/meyering/w/co/coreutils/src'
   CC  version.o
   CC  uname.o
   CC  hostid.o
   ...

Subject: [PATCH] build: use automake's new $(AM_V_GEN) and $(AM_V_at) variables

* src/Makefile.am (dircolors.h, wheel-size.h, wheel.h, fs.h):
(version.c, version.h): Mark with $(AM_V_GEN) and $(AM_V_at),
so that the latest automake prints "GEN $@" by default.
