bug#8665: [PATCH 2/3] refactor: silent rules handling (a little)

[Stefano Lattarini]

* automake.in (handle_languages): Move definition of $(AM_V_GEN)
variable ...
(define_verbose_tagvar): ... and of '$(AM_V_at)' variable ...
(handle_silent): ... in this new subroutine.
(generate_makefile): Call it.
